Propylaea
Over the centuries, the Propylaea serves as a palace for a Byzantine bishop and as a residence for a Turkish governor, but in the mid-17th century, the gunpowder stored in the Propylaea caused a severe explosion, damaging the building. However, restoration work during the 20th and 21st centuries has allowed it to regain some of its previous splendor.
