This small oasis on the Batinah coast is located in northern Fujairah, between Khor Fakkan and Dibba. Bidya is well-known to travellers because of its unusual and very old, twin-domed mosque, generally considered the oldest mosque in the UAE But the history of Bidya extends much further back in time. A third millennium round tower, comparable to the ones excavated at Tell Abraq and Hili 8, marks the existence of an important site here c. 2500-2000 BC A long, semi-subterranean grave, very similar to the one excavated at Qattarah in the Al Ain oasis, is located nearby. Material from secondary burial within the tomb, including glazed Parthian pottery similar to that found at Al-Dur and Mileiha, also occurs. Finally, the poorly preserved remains of a Portuguese fort have recently been excavated by an Australian expedition.
