The Sultan Alaaddin Mosque is an important Ottoman structure located in the city center of Antalya, in the Kaleiçi district. The Sultan Alaaddin Mosque is a mosque from the early Ottoman period and is integrated into the city's historical fabric.

The Sultan Alaaddin Mosque was built in the late 13th century on the orders of Seljuk Sultan Alaaddin Keykubad. However, the stones and workmanship used during the construction of the mosque, while in the Ottoman style, also reflect Seljuk architectural influences. This makes the mosque an important example of the fusion of both Seljuk and Ottoman architecture.

The mosque is notable for its central dome and wooden pulpit. Additionally, the library and ceramic decorations on the walls of the mosque highlight its importance in art history. The wooden ceiling, intricate craftsmanship, and ornate pulpit in the interior reflect the architectural elegance of the period.

The mosque is surrounded by a large courtyard and high walls. The interior is quite simple, yet decorated with stone carvings and geometric patterns that bear traces of Seljuk design. The fountain at the front of the mosque was historically used for water supply.

The Sultan Alaaddin Mosque has undergone several repairs over time. However, the historical fabric and architecture of the building have largely been preserved, and the mosque is still actively used today. As one of Antalya's historic mosques, it is both a place of worship and a site of interest for visitors.
