Perched on a rocky promontory above the lively harbor, Marmaris Castle is one of the city’s most memorable landmarks, offering expansive views along the Mediterranean coast from its lookout towers. Although the present-day castle was built by Süleyman the Magnificent in 1522, archeologists estimate that a castle has stood on the waterfront plot since as early as 3000 B.C., making it one of the region’s oldest landmarks.
Marmaris Castle is also home to the city’s principal museum, the Marmaris Archaeology Museum, which retells the story of its construction and one-time military prominence while also displaying ancient armory, sculptures and other artifacts excavated from Marmaris, Knidos and Hisarönü.
Marmaris Castle & Museum are located on the Marmaris waterfront, east of Marmaris Beach. They are open Tuesday through Sunday, and admission is 5YTL.
