Although today the city walls are in ruin, still are splendid and impressive and many of the original gates have survived to our day. As a result of the restoration that began in the 1980’s, the vicinity of the walls has been improved and the some areas turned into public parks.
The most impressive gate in the walls was the “Golden Gate”. That door was build as an triumph arch and when victorious armies returning from a war entering through this door. In Teodosius period the city walls was enlarged and Golden Gate became a part of city walls. During Ottoman period three more towers was added inside the walls connected with four curtain walls to the city walls and formed a five sided inner castle. These added parts in Ottoman period called seven towers but never they were used as a castle, they were used as prison and storage places.
Today seven towers restored in 1959 and serve as a museum. In summer time concerts and other cultural activities take place here
