The site is believed to have been an Ionian fortification dating back to 3000 BC before the Ottoman renovation.
During World War I, the castle sustained damage from French naval shelling, leading to a long period of decay before its late 20th-century restoration.
The museum complex consists of seven indoor halls, one of which is dedicated specifically to maritime and local ethnographic findings.
The castle walls are constructed primarily from locally sourced stone, reflecting the architectural techniques of 16th-century Ottoman military engineering.
Archaeological finds displayed in the museum include amphorae recovered from underwater shipwrecks in the Aegean Sea.
Marmaris Castle, originally constructed in 1522 under the orders of Suleiman the Magnificent, served as a military base for the conquest of Rhodes. The structure incorporates defensive walls and a collection of arched rooms repurposed as an archeology museum. The facility houses local artifacts recovered from regional excavations, including Hellenistic, Roman, and Byzantine pottery and coins. The castle is positioned on a hill overlooking the Marmaris harbor and the old town district. Visitors can access the ramparts, which provide a 360-degree view of the bay and the surrounding coastline. The site underwent significant restoration in the 1980s to preserve its masonry and historical architecture. It is situated within the historic Tepe neighborhood, characterized by traditional narrow cobblestone streets.
