The Turban Grand Yazıcı Hotel in Marmaris, Turkey, was raided by coup plotters on July 15, 2016.
The hotel was used as a base by President Recep Tayyip Erdoğan and his security team, and it was the site of a fierce gun battle.
The hotel has been preserved as it was on that night, with the rooms used by Erdoğan and his security team kept closed and untouched.
The windows of the rooms are still broken, and there are bullet holes and grenade marks on the walls.
The bullet holes have been numbered, and the prayer rug and rosary that Çetin was using when he was killed are still there.
The hotel's owner, Serkan Yazıcı, has said that he wants to preserve the rooms as a memorial to the events of July 15.
He said that he wants people to be able to see the damage that was caused and to remember the sacrifices that were made that night.
