Museum · research institute › Argyrokastrou Square, Collachium
The First Hospital of the Knights stands at the north-western, Argyrokastrou Square end of the Street of the Knights, within the Collachium, the fortified Knights’ Quarter of the medieval town — directly opposite the Inn of the Tongue of Auvergne, and at the far end of the same street from the later Great Hospital. It served the Order’s charitable and medical mission from the mid-14th century until 1483, when that mission passed to the newly completed Great Hospital.
A new idea: the hospital as medicine, not almonry
12th–14th c. › from pilgrim hospice to medical institution
By the Order’s own Jerusalem-era statutes of 1182, its hospital had already moved decisively from a general shelter for weary pilgrims toward a genuinely clinical model, with physicians under oath, dietary regimes for the sick, and hygiene measures with no real precedent in the medieval West. Founded within a generation of the Order’s final withdrawal from the Levant, the First Hospital of Rhodes re-established that same tradition on Rhodian soil — serving, in Roger de Pins’s own words, “the pilgrims, the poor, and the sick poor” together, a threefold clientele the later Great Hospital would narrow to the sick and wounded alone.
What survives
Argyrokastrou Square › a modest Gothic precursor to the Great Hospital
The surviving building occupies the north side of the east end of the Street of the Knights, its main entrance opening at ground level into the central, oldest part of the building, whose rooms have vaulted ceilings. Between 1355 and 1365, under Grand Master Roger de Pins, a two-hall building was added to the north; neither that addition nor a later south hall survives today. Restoration under the Italian administration in the 1920s, and again after the Second World War, gave the building its present form as the Archaeological Institute of the Dodecanese.
Persons & events
1099–1952 › from Jerusalem to the Archaeological Institute
A monument whose biography runs from the Order’s Jerusalem institutional origins, through half a century of incremental Rhodian construction under five Grand Masters, to its supersession in 1483 and its 20th-century second life as a research institute.

“Hospitale lectorum magnum pro peregrinis et infirmis” — a great hospital of beds for pilgrims and the sick.

Rhodes & the wider Mediterranean, 1356–1780 › a narrative reconstruction for visitors
A thematic narrative composed for visitor interpretation, setting Grand Master Roger de Pins’s charitable statute against the broader Mediterranean slave economy the Order’s hospital stood against. It draws on wider historical scholarship on Mediterranean slavery and piracy rather than on sources specific to this building, and should be read as interpretive context, not as a claim of verified fact for every figure cited.
Slavery in the Muslim Middle East and Africa was not a matter of race but of religion: slaves were infidels, and their masters could devise for them almost any cruelty. At least 80% of those captured by Muslim slave traders are estimated to have died before ever reaching a slave market. Between 1530 and 1780, some 1.5 million white European Christians were enslaved by the Muslim corsairs of the Barbary Coast — against roughly 800,000 Black Africans carried by the Atlantic slave trade to the Americas over the same span. Historians of the trade put the total toll of Muslim slave raids into Africa at over 140 million people.
Piracy forced Spain and Italy to turn their backs on the sea, abandoning centuries of trading and seafaring tradition. In 1535 Charles V liberated Tunis and freed 20,000 Christian captives. Slaves were so plentiful and so cheap that owners worked them to death and simply bought replacements; the price of a slave fell so low that buyers are said to have traded one for an onion. Churches were desecrated, their bells stolen for the value of the metal and to silence the Christian voice that might otherwise call the town to its own defence. The Ottoman Turks introduced the child levy to recruit their army; noble and wealthy captives were ransomed for great sums, Jews bought back at high prices by their own families, and high clergy by the Vatican. Slaves destined for the Muslim Middle East were put to sexual exploitation and military service alike: male captives were castrated, and children born to enslaved women were killed at birth.
Against this economy of cruelty, the Knights Hospitaller held to the charitable and medical vocation that has rooted their Rule from the twelfth century to today. Grand Master Roger de Pins (1355–1365) built the First Hospital’s northern hall. During the earthquake of 1364 and the plague that followed, de Pins offered his own fortune to relieve the sick and the poor, earning him the name “the Charitable.” Enriched by two centuries of accumulated medical knowledge from their years in the Holy Land, the Hospitallers nursed men and women alike, independently of creed, origin or social status — a standard of care that, set beside the traffic in human beings across the wider Mediterranean world, was itself a quiet act of resistance.

Statement of significance
“Hospitale lectorum magnum pro peregrinis et infirmis.” (“A great hospital of beds for pilgrims and the sick.”)
The First Hospital of the Knights is of outstanding historical significance as the earliest-attested purpose-built expression, on Rhodes, of the Hospitaller Order’s founding charitable vocation, and as the direct architectural and institutional precursor of the Great Hospital that succeeded it. Distinctively, and unlike its successor, it served pilgrims and the sick together — attested by contemporary pilgrim witnesses Nicolò de Martoni (1394), the Seigneur d’Anglure (1395) and Ruy González de Clavijo (1403), and by Grand Master Roger de Pins’s own statute of 1357. The building should be understood as a genuine, if less publicly accessible, contributing structure within the Collachium ensemble rather than as one of the property’s three headline monuments. Taken together, it merits an Importance Level of National to International significance: a rare and historically exceptional surviving example of the Order’s earliest Rhodian hospital building, documented across five successive Grand Masters’ patronage, and the direct precursor, architecturally and institutionally, of the Great Hospital of the Knights. The charitable mission it first housed on Rhodes did not end with the Order’s departure in 1522–23, but found its fullest later expression in the Order’s Valletta Infirmary on Malta.
