Galata Tower is a well known site in Istanbul for the fact that Hezarfen Ahmet Celebi flew from the tower in the 17th century.
When you are in the Istiklal Street in Beyoglu, you should definitely do all the way down to the “Tunel” section where the 1st stop of the tram is located along with the funicular that leads to Eminonu, a historic part of the city that was once known to be the center. The one and only Lomo Store is also located near by :) Also, right around the corner is the Galata Tower.
Galata Tower is one of the oldest towers on the world and has been built around the 500s. The tower came to the Ottoman rule with the conquest of Istanbul in 1453 and was used as a prison at first and then as a fire patrol tower. The main action that brought fame to the tower came in the 17th century when Hezarfen Ahmet Celebi used hand made wings to fly off and land Uskudar which is located on the Asian side of the city. He was considered as a scientist on his own terms and was a unique character. He was sent to exile by the Sultan due to fact that he was seen as dangerous and tower was used for fire patrol once again.
The current touristic state came in the 1960’s and nowadays it holds a cafe, a restaurant and even a night club where you can enjoy some authentic Turkish belly dancing. Also the top floor balcony is open to public to view all the way from Golden Horn region to the Asian side of the city. And if you are there on a sunny day, you can make great use of this area to shoot photos of almost all of the historic places within sight.
