The Tower of David, also known as the Citadel, is an ancient citadel located near the Jaffa Gate entrance to the Old City of Jerusalem.
The citadel that stands today dates to the Mamluk and Ottoman periods. It was built on the site of a series of earlier ancient fortifications of the Hasmonean, Herodian, Byzantine and Early Muslim periods, after being destroyed repeatedly during the last decades of Crusader presence in the Holy Land by their Muslim enemies. It contains important archaeological finds dating back over 2,500 years including a quarry dated to the First Temple period, and is a popular venue for benefit events, craft shows, concerts, and sound-and-light performances.
Dan Bahat, the Israeli archeologist, writes that the original three Hasmonean towers standing in this area of the city were altered by Herod, and that "The northeastern tower was replaced by a much larger, more massive tower, dubbed the "Tower of David" beginning in the 5th century C.E."
