The Hospitallers were a military order devoted to care for the sick in the Holy Land and they built this citadel. Acre’s Hospitaller quarter houses three main buildings: the headquarters (Knights’ Halls); St. John’s Church and the hospital south of the church.
Under Saladin’s command, the Muslim captured this city in 1187 but in 1191, following a two-year siege, King Richard the Lionheart took Acre back from the Muslims. The Hospitaller Order transferred its headquarters to Acre from Jerusalem once city was re-taken. The Battle of Acre resulted in the fall of the city to the Mamluks of Egypt on 18 May 1291.
