Yedikule Fortress

Marmara seen from Yedikule Hısarı 7oct14

Here we see the Sea of Marmara from the northern-most tower at Yedikule Fortress (Yedikule Hısarı). Yedikule, which means seven towers, was built in 1458 as an addition to the Theodosian Walls which were built in the 5th Century. Yedikule is at the southeastern edge of the old city. You can see the fortress (‘from space‘) if you are zoomed in close enough on this map. A short description of Yedikule Fortress can be found here; a slightly longer version, here.
