House of Saint Ananias, also called Chapel of Saint Ananias, is an ancient underground structure located in Damascus, Syria. The place is alleged to be the remains of the home of Ananias of Damascus, where Ananias baptized Saul (who became Paul the Apostle). Archaeological excavations found the remains of a Byzantine church from the 5th or 6th century AD, adding physical evidence to support local tradition that the chapel has an early-Christian origin from the 1st or 2nd century AD. The church was inscribed as a UNESCO World Heritage Site in 1979 as part of Ancient City of Damascus.
