In the neighborhood of the fortifications lay the famous Prison of St. Diomed. This prison witnessed several notable historical events. In 654, Pope Martin I was detained here by Emperor Constans. His confinement is recorded in historical sources, including his fifteenth Epistle, which details the harsh treatment he endured while in Constantinople.
Later, during the Byzantine era, the prison held Maria, the wife of Manuel Comnenus and mother of Alexius II. She was imprisoned by the infamous Andronicus Comnenus, a ruler notorious for his cruelty.

The Final Tower and Its Castle
The last tower in this line of walls is situated on a small promontory, offering a commanding view of the Sea of Marmara. The tower is visually striking and remarkably well preserved in parts. It has four stories and is built mainly from large marble blocks, giving it a solid and imposing appearance.
Attached to the tower was a two-story building, forming a small castle or chateau. Although only the foundations of the western and northern walls remain, the eastern wall is nearly intact. This wall contains two tiers of small windows and is decorated with string-courses, suggesting it was both functional and ornamental. The castle likely served as the residence of a high-ranking military officer, responsible for overseeing this important section of the city walls. Many historians believe that the Prison of St. Diomed was located within this castle. A small postern, or secondary gate, existed along the shore near the tower for use by the garrison stationed there.
