The Red Tower is an octagonal Seljuk period work that has become the symbol of Alanya. In this special tower, the name of the master who built the building is indicated on the wall to the right of the entrance door. In addition to its plain structure, the octagon is quite complex in its planning, contrary to its external appearance. Kizilkule has five floors: ground floor, first floor, mezzanine, open floor and open terrace
