About 450 metres from the western entrance of Madhat Pasha Street, in a stretch covered with a large metal dome, is a small mosque with a balcony in the form of a pulpit that serves as a minaret, called Jakmak or Sheikh Nabhan Mosque. It is here that the Christian tradition locates the house of Judas, the place where Saul remained for three days without eating or drinking and was baptized at the hands of Ananias (Acts 9:9). The Christians of Damascus say the mosque was built over the ruins of an ancient church that commemorated the episode narrated in the Acts of Apostles. Today, the nearby House of Saint Ananias commemorates the event.
