Photo of the Mariamne Tower of the Citadel in the Second Temple Model
King Herod built the three heavily fortified towers of the citadel upon a location that was already a very fortified position since the days of Solomon. Jerusalem's citadel was the highest point of the city about 2500 feet above sea level. Herod built the citadel and towers to protect the western side of the city of Jerusalem and his marvelous palace. These were fantastic towers, the largest was the Phasael Tower but the most beautiful was his Mariamne Tower.
The Phasael Tower
1. Phasael Tower (the largest, named after his brother stood 145 feet high).
3. Mariamme Tower (named after his beloved Hasmonean wife whom he had murdered. Josephus said "the king considering it appropriate that the tower named after a woman should surpass in decoration those called after men." It stood 74 feet high).
When Titus destroyed most of Jerusalem in 70 AD., he spared Herod's fortress.
Nothing remains of Herod's three towers and a Citadel named "David's Tower" stands on the spot of a Phasael’s Tower.
