Halepa Monastery was founded at the end of the era of Venetian rule and, according to documents dating back to 1555, it owned a significant amount of property.
The founder, according to an inscription at the Monastery, was Ieremias Sgouros in 1637. The monastery was destroyed during the Ottoman era but was subsequently reconstructed.
Its catholicon is situated in the middle of the courtyard, but unfortunately only ruins remain. This is a two-aisled domed basilica dedicated to the Birth of Jesus and the Transfiguration of the Saviour. In the 19th century, Abbot Ploumis wanted to build a larger church around the catholicon, but this work was never completed. The Church of Agia Marina is located just outside the Monastery.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
