The streets are narrow, wooden buildings are furnished with balconies, just like the other Ottoman cities.
The only written reference mentioning about the construction of Marmaris Fort that is located at a high point at the back of the Yacht Harbor, is the travel book (Seyahatname) of Evliya Çelebi. Evliya Çelebi, who visited Muğla and its surroundings in 17th century, says that Kanuni Sultan Süleyman had ordered the repair of the fort before his Rhodes campaign and that the fort was used as a base during the campaign. In his Seyahatname Evliya says that “the fort was constructed on the main rock having four emplacements, that there were 400 foot walls made of smooth stones with an inscription on the entrance door, that there was one room for each of warden, imam, mosque caretaker and the guardians. Some sources on the other hand say that Kanuni had ordered the fort to be built after his return from the Rhodes campaign. Inside of the fort that had been destroyed during the First World War with the cannon balls of a French destroyer, had been used for settlement beginning from the pre-Rebublic period until recently 18 houses remained.
