Antalya’s most distinctive landmark is the Yivli Minare (fluted minaret) built by the Seljuk sultan Alaeddin Keykubad (1219-36). The minaret is a typical example of Seljuk architecture, with a square base surmounted by an octagonal drum bearing the fluted shaft, with its corbelled gallery around the top. The attached 14th-century mosque is still in use today. The minaret is right beside the Kale entrance gate into the old city. Opposite the minaret is Antalya’s Ottoman era clock tower, while nearby are some tombs dating from the 14th century.
