The oldest mosque in the United Arab Emirates, about 35 kilometres north of Fujairah city, is one of the country's, and the Emirate of Fujairah's, most important historical sites. Built on a low hillside overlooking the Arabian Sea, and guarded by two watchtowers, its origins remaining largely a mystery. Famous for its unique compact mud-brick structure, it has four pointed domes resting on one single internal pillar.
