Alanya Shipyard and Alanya Tophanesi are the historical buildings of Alanya from the Seljuk period.

The construction of the shipyard was started in 1228 near Kızılkule, six years after the Anatolian Seljuk Sultan Alaeddin Keykubad I took the city and was completed in one year. The shipyard, which consists of five arched eyes, has a sea-facing façade of 56.5 meters and a depth of 44 meters. The location chosen for the shipyard was planned to maximize the use of daylight. The inscription on the entrance gate of the shipyard bears the coat of arms of Sultan Keykubat and is decorated with rosettes.

Alanya Shipyard is the first Seljuk shipyard in the Mediterranean. Alaaddin Keykubat, who had previously built the Sinop Shipyard in the Black Sea, took the title of "sultan of two seas" with the Alanya Shipyard. A masjid is on one side of the shipyard, and a guard room is on the other. There is a well in one of the eyes, which was blinded in time. The entrance to the shipyard, which can be reached by boats from the sea or on foot from the city walls next to Kızılkule, is free of charge.
