The Sanctuary of Promachona was probably dedicated to the worship of Aphrodite or Artemis Soteira. In the temple stands the base of the cult statue, and in front of the temple the marble altar. The sanctuary was completely destroyed in the raid of 69 B.C. Two years later Gaius Triarios built a bastion of walls over the temple which were supposed to protect the remains of the city.
