Church of St John the Baptist (Hospitaller, Acre)

The church was founded by the Hospitallers after the capture of Acre in 1104, and served as their principal place of worship and burial within the order's vast fortified commandery.^[3] Dedicated to John the Baptist, it stood adjacent to the Hospitaller refectory and hospital wings and was one of the largest ecclesiastical buildings in the Crusader city.^[2][3]

Archaeological excavations have revealed portions of its crypt, apsidal foundations, and marble flooring beneath the Ottoman citadel. Six parallel vaulted halls with traces of Gothic ribs survive below ground level, while fragments of columns, capitals, and tracery indicate a substantial three-aisled church.^[2][4]

The church was destroyed following the Fall of Acre in 1291. Its remains were later incorporated into Ottoman military and administrative buildings, including the present Citadel of Acre and the Serail complex.^[5]
