UNESCO-listed Medieval City of Rhodes · Ippokratous (Hippocrates) Square, the Borgo

Castellania

UNESCO World Heritage emblem

A richly sculpted civic building of 1507, built under Grand Master Émery d’Amboise at the harbour end of the Hospitaller Borgo’s great common square — popularly and officially known as the Castellania, court and prison of the Order’s castellan, though specialist scholarship disputes whether the standing building ever actually housed that institution. Fish market and mosque under the Ottomans, restored by Italy in the 1920s–30s, it has served since 1947 as the Public Library of Rhodes and the Historical and Folklore Archive of the Dodecanese.

Site & dates

Ippokratous Square › harbour end of the Hospitaller Borgo, reached via Aristotelous Street

The building traditionally known as the Castellania occupies the eastern end of Ippokratous (Hippocrates) Square, at the harbour edge of the Hospitaller Borgo — the merchants’ and townspeople’s quarter south of the fortified Collachium. Its principal, west-facing façade and monumental external staircase thrust into the square itself, while its rear (north-east) side is built into the town’s harbour-front sea wall. Dated by its own sculpted heraldry to 1507, it is traditionally identified as the office and court of the Hospitaller castellan, though this identification is disputed by specialist scholarship (see §01, below).

Identity Debate

Whose Castellania?

1356–2013 › an institution, a building, and a genuinely open question

The castellania, as an institution — the office and court of the Hospitaller castellan, responsible for urban justice and administration, with attached prison facilities — is independently and securely documented from the mid-fourteenth century, more than a century before the standing building’s own 1507 construction. Whether the standing Ippokratous Square building is, in fact, that institution’s historical seat is a genuinely open scholarly question. The historian Jean-Bernard de Vaivre argues, on detailed archival and topographical grounds, that the documented châtellenie must be situated instead near the Marine Gate, inside the fortified Collachium. The architect Katerina Manoussou-Della goes further still, identifying the standing building as the distinct Hospitaller institution of the commercium (Commercial Court), and locating the true judicial castellania near the site of the Order’s first Hospital of 1311. A third, independent lead in the Italian Ephorate’s own 1930s photographic archive points to yet a further candidate site, on Sokratous Street.

None of this disputes the building itself
No scholarship disputes the standing building’s own construction date of 1507 or its d’Amboise-period heraldry; the dispute concerns only which Hospitaller-period institution it actually housed, and where the judicial castellania named in the fourteenth- and fifteenth-century sources truly stood.
Retained by this Statement
This Statement concerns the building officially designated, administered and popularly known today as the Castellania, while recording transparently that its identification with the judicial institution of that name is disputed by more than one line of specialist scholarship.

What survives

Ground floor and piano nobile › a plan without an internal stair

The standing building comprises a ground floor of two large arched shops or warehouses opening onto the square through an open loggia, adorned by two semicircular cross-vaults, and an upper floor reached only by the exterior staircase — a plan without any internal, ground-to-first-floor stair, consistent with a ground floor let or used independently of the institution housed above. Its present exterior form is substantially the product of the 1925–1935 Italian restoration, whose fidelity to the Hospitaller-period original has not been independently verified for this document.

The exterior staircase and the “Cellar of the Knights”
A broad stone staircase, likened by the SATI record sheet to Aegean-island domestic staircases, rises from the square to the first-floor entrance; the vaulted space beneath it is known today, in library and popular usage, as the “Cellar of the Knights.”
The first-floor window and the 1507 heraldry
A large window divided into four lights by a marble cross with fleur-de-lys finials, set in a Gothic flamboyant arch, with the sculpted arms of Grand Master Émery d’Amboise placed beside it amid carved foliate ornament.
The Angel Doorway
A second, Renaissance-profiled doorway further along the terrace carries, on its lintel, the arms of the Order, of d’Amboise, of Bailli Philippe Villiers de l’Isle-Adam and of the knight Jacques Aymer, grouped around a carved angel.
Crocodile spouts and painted ceilings
Three stone water-spouts carved as crocodiles — a motif shared with the Inn of the Tongue of France — and, in the upper chamber, a fully intact painted and inlaid ceiling depicting ancient philosophers and the human virtues.

History

Persons & events

1309–1948 › the Borgo, the court, the fire, and the transfer to Greece

The Knights Hospitaller took possession of Rhodes in 1309, dividing the town into the fortified Collachium and the Borgo, the merchants’ and townspeople’s quarter to the south, centred on the “magna et communis platea” — the great and common square on which the standing building was later erected. The building’s own later history is one of repeated functional transformation, from a Hospitaller-period civic building, through Ottoman commercial and religious use, to its present civic role as a public library and archive.

1356–1503, the castellania documented
A “hospicium castellanie” is recorded in 1380 as having housed the castellan’s office, court and prison since 1356; four dated criminal cases (1433–1490) and a professionally staffed judicial apparatus of named judges and notaries corroborate a continuously functioning institution.
1507, construction under Émery d’Amboise
The standing building is dated by its own sculpted heraldry to 1507; its close architectural and heraldic kinship with the Inn of the Tongue of France (1509–1519) has led scholars to speculate, without documentary proof, that the same masons built both.
1522–1924, Ottoman fish market and mosque
Converted after the 1522 conquest to a ground-floor fish market with the Bejesten Jami mosque above; progressively encroached upon by market shops until a 1924 fire exposed the buried Hospitaller fabric.
1925–1935, Florestano di Fausto’s restoration
The Italian colonial administration of the Dodecanese restored the building, clearing later accretions and reinstating its exterior essentially in the form seen today.
1947–48, transfer to Greece
The Treaty of Peace with Italy (10 February 1947) provided for the Dodecanese’s transfer to Greece, taking effect in 1948; since 1947 the building has housed the Public Library of Rhodes and the Historical and Folklore Archive of the Dodecanese.
2009–2013, the location debate renewed
Jean-Bernard de Vaivre (2009) and Katerina Manoussou-Della (2013) independently reopen the question of the castellania’s true historical seat, discussed fully in §01, above.

Testimony

Eye witness

1380–2013 › four documents and a scholar’s own words

A house of the castellania, 1380

A “hospicium castellanie” (house of the castellania) is recorded in 1380 as having, since 1356, housed the office and court of the castellan together with a prison, standing close to the town’s walls and a stair giving access to the wall-walk — the earliest secure documentary trace of the institution the standing building would later be named for.

Archival record of 1380, cited via de Vaivre and Manoussou-Della.
Ninety-seven paces from the Marine Gate, 1480

A detailed 1480 topographical description of the city situates the castellania precisely at the corner of the great Trecenal (shipyard) square, giving paced distances between it and nearby landmarks: from the Marine Gate to the castellania, 97 paces; from the castellania to the house and tower of the Order’s Treasurer, eight towers and 310 paces — a itinerary de Vaivre reads as placing the institution near the Marine Gate, well inside the Collachium.

1480 topographical description, published in detail by Jean-Bernard de Vaivre, 2009.
Pilloried for holding a hand, 1490

In 1490 the Greek Rhodian Anthony Mavros was pilloried, given one hundred lashes, jailed for two months and degraded to metic status — for holding the hand of the Castellan of Trianda to avoid a blow. One of four individually dated criminal cases (1433–1490) presided over personally by successive Grand Masters, documenting the castellania’s judicial activity as an institution, though none can be shown to have been heard inside the standing 1507 building itself.

Hospitaller judicial record, 1490, cross-corroborated in the project’s Heritage Narrative and SATI II documentation.
“Today, wrongly in my opinion”

Synthesising the 1380, 1475, 1477, 1480 and 1491 archival records together with a soldier’s eyewitness account of the 1480 siege, the architect Katerina Manoussou-Della states her own view directly: the standing monumental building on Ippokratous Square is “today, wrongly in my opinion, known as the castellania” — identifying it instead as the Hospitaller-period commercium, the Commercial Court, and proposing that the “Castellania” name migrated from an adjoining gate, already called the “castellania Gate” by 1475.

Story

Justice

Castellania, 1507 › a narrative reconstruction for visitors

A dramatised account, written for visitor interpretation and drawing on the four documented court cases and the building's own fabric (see Testimony and Fabric, above). It is a narrative device, not a literal historical record.

Crime of Passion

According to the public law, murder is a crime that leads to the death penalty, especially if not committed for reasons of self-defence. On the 20th of October 1433 Grand Master Fluvià acquits the caulker George Kokkinos, who has in fight mortally wounded the Rhodian citizen Cosmas Crussochiris. The Draper of the Order, Ludovico de Galbis, the nobleman Jean de Conpyes and Knight de Gouffry explicitly declare that the act is not pre-meditated and the defendant is set free. On the 22nd of May 1442 Grand Master de Lastic acquits Michael Turquomano from Rhodes, who killed his wife, because she has provoked many scandals. Michael has not premeditated the murder and was a good citizen.

Crime for Profit

Fantino Quirini, Admiral of the Order, is a real merchant of Venice. He does not have any moral inhibitions to deal with the enemy for profit. He buys soap, sugar and pepper from pirates, who have seized the goods from Rhodian ships! Fantino has his own shipyard and rents the ships for commercial profit. On the 1st of February 1449 Grand Master de Lastic is outraged: Admiral Quirini denies food supplies to the Knights in Petroumi, this very bastion of the Christian world in Asia Minor. De Lastic is sending the higher official of the Order, the Castellan of Amposta, John de Villalba, to Kos to find out if Quirini has obeyed the order to supply Petroumi.

Blind Justice

In 1490, to avoid a blow, the Greek Rhodian Anthony Mavros holds the hand of the Castellan of Trianda. Questioning the Order’s authority is not tolerated: attached to a wooden framework erected on a post, with holes for securing the head and hands, exposed to public mockery, Mavros receives 100 lashes by the bullwhip, goes to jail for two months and is degraded to the class of metics, just a step above the slave.

Court of Law

Being the Court of Law, Castellania lies in the middle of the Medieval Market. On the ground floor survive two arched warehouses and a gallery with cross-vaults. The broad staircase leads into the first floor and the terrace. The arms of Grand Master d’Amboise are on the walls. There is strong similarity between Castellania and the Inn of France in the Street of the Knights. Has Grand Master d’Amboise built both buildings using the same team of masons?

Assessment

Significance criteria

Nine-criteria framework › National to International importance

Rarity
A largely intact, richly decorated early-sixteenth-century civic building surviving within the commercial Borgo, rather than the better-preserved Collachium; its concentration of multiple named individuals’ heraldry in a single decorative programme is unusual among surviving Rhodes monuments.
High
Representativeness
Representative of early-sixteenth-century Hospitaller civic architecture in the Borgo and, on the traditional identification, of the Order’s judicial administration — qualified by specialist scholarship disputing whether the building represents the castellania at all, or the distinct commercium.
Moderate to High
Aesthetic value
A flamboyant-Gothic window with marble cross and fleur-de-lys tracery, a Renaissance-profiled angel doorway, and a sculptural programme of heraldry and crocodile water-spouts among the more refined surviving examples of Hospitaller architectural sculpture on Rhodes — reflecting both surviving 1507 fabric and the 1925–1935 restoration.
High
Integrity
Qualified on several grounds: four centuries buried beneath Ottoman-period shopfronts; a standing exterior substantially the product of unverified 1925–1935 restoration; and, most fundamentally, a building whose very identification as “the Castellania” is disputed by specialist scholarship.
Low to Moderate
Historical value
Substantial value both for its own documented 1507 construction and heraldry, and for the well-documented judicial institution traditionally associated with it, spanning four dated criminal cases (1433–1490); further and unusually richly augmented by its status as the focus of a live, well-documented topographical dispute among specialist historians.
High
Symbolic & social value
As the building popularly identified with the Order’s justice and, since 1947, as home to the Public Library of Rhodes and the Historical and Folklore Archive of the Dodecanese, the Castellania carries strong symbolic and social value as a continuous site of public administration and civic life spanning more than five centuries.
High
Scientific value
The subject of active, unresolved scholarly research into its Hospitaller-period institutional identity and the true location of the châtellenie/castellania; its own construction phases also offer research potential for the study of adaptive reuse across four distinct political administrations of Rhodes.
High
Interpretive potential
A single monument through which visitors can trace Hospitaller civic justice, Renaissance sculpture and heraldry, Ottoman-period conversion, Italian restoration and a modern civic afterlife — plus a genuinely live scholarly controversy over its own identity, an unusually accessible way to introduce visitors to how heritage scholarship actually works.
High
Importance level
A contributing component of the UNESCO-inscribed Medieval City of Rhodes, protected under Greek Archaeological Law, and a building of genuine and ongoing interest to international scholarship on the topography and civic institutions of Hospitaller Rhodes.
National to International

Statement of significance

“Castellania.” (traditional identification; also recorded as “Basilica Mercatorum” in some modern documentation)

The Castellania stands at the harbour end of Ippokratous Square, at the heart of the Hospitaller-period Borgo of the UNESCO-listed Medieval City of Rhodes. It is of high historical and scientific value both for its own well-documented construction and decorative programme of 1507 and, unusually among the monuments of Rhodes, as the live subject of an unresolved topographical and institutional debate among specialist historians — a debate that makes the building, and the scholarship surrounding it, a valuable case study in how the historical topography of Hospitaller Rhodes continues to be actively researched and revised. It is of high symbolic and social value as a continuous site of public civic function across more than five centuries, and of high aesthetic value for its sculpted Gothic and early-Renaissance façade. This significance must be assessed together with an honest acknowledgement of the building’s integrity: its present exterior form is substantially the product of the 1925–1935 Italian restoration, whose fidelity to the Hospitaller-period original has not been independently verified for this document, and its very identification with the castellania institution named in its traditional title is contested by credible specialist scholarship. Notwithstanding these qualifications, taken together the Castellania merits an Importance Level of National to International significance: a contributing component of the UNESCO-inscribed Medieval City of Rhodes, protected under Greek Archaeological Law, and a building of genuine and ongoing interest to international scholarship on the topography and civic institutions of Hospitaller Rhodes. Any conservation, research or interpretive use of the building should present this layered and disputed history transparently, rather than asserting the traditional identification as settled fact.
