The man managed to reach about 10 meters in altitude, sat down on the railings and fell asleep shortly after, eyewitnesses said.
Locals of Bursa's İnegöl district noticed the man on the tower around 6 p.m. and called law enforcement to the scene.
Police arrived on the scene with health workers, tried to wake up the sleeping man by shouting at him for a while, and were finally successful.
The man was able to climb down the tower on his own after waking up to the police's alerts.
