"Gelibolu is a very large but undefended settlement located in the Dardanelles of Greece (Romania Strait). It has a square stone castle on the seashore with eight small towers built into high walls. The surrounding moats are established on the land side, while those on the sea side are not deep but filled with water. Just below the castle, there is a small good harbor and galleys. Right on the seashore, to protect the harbor, there is a beautiful square tower built on solid ground, towards the castle. On the other side, a wall is built in the sea, and this wall is used to lock the harbor. Due to this small passage made of walls and beams leading to the galleys, there is no chain at the entrance of the harbor.
When I visited the harbor, there were four galleys and many boats. As is customary, the Turks protect this place with a large number of galleys, in a manner quite different from other regions. On the Turkish shore directly opposite Gelibolu, there is a very beautiful tower on the strait's shore. The Turks generally cross from here. The strait is three or four miles wide here. And when this harbor and castle were conquered by the Turks, since there was no safe crossing from side to side, the lands they obtained from the Greek side gradually fell into ruin.
The distance from Istanbul to Gelibolu is one hundred and fifty miles."
