Located in the Tabakhane district, the Great Mosque is the oldest structure of Menteşe — and of Muğla itself. It was commissioned in 1334 by Menteşe Bey İbrahim Bey; that is, it has a history spanning over 690 years. This makes it one of Turkey's oldest mosques from the Beylik period.
The building carries Seljuk architectural influence, constructed from ashlar stone with a single-minaret tower. Its roof is entirely wooden — a significant feature in 14th-century Anatolian mosque architecture. In 1938, it was restored by the local notable Abdizade Bey, with its original architecture carefully preserved; during this restoration, the congregation area and ablution facilities were added.
The mosque's original inscription still remains in place — one of the period's rare epigraphic documents.
