Hidirlik Tower was built in the 2nd century, is one of the three surviving symbols that are left from the Roman era, along with Hadrian's Gate and the Broken Minaret. It is 14 meters high and made from yellow-brown, stone blocks. The entrance is on the east, and a small room that has some worn frescoes in it has a staircase going up to the top. There is no certain information about who built it and why; however, the rumors are claiming that it may be the tomb of a hero, it was built as a lighthouse or a watchhouse, it was once a church. Even if there is no evidence to support any of these claims, today it is a popular photo and sundown watching spot for local and foreign visitors. It is a short walk from Hadrian’s Gate and the Broken Minaret as well.
