Dhayah Fort

Dhayah Fort (Arabic: قلعة ضاية) is an 18th-century fortification in Ras Al Khaimah, United Arab Emirates (UAE). It is the highest hilltop fort in the UAE and was the site of a battle during the Persian Gulf campaign of 1819, when British troops captured the fort after a brief siege.

The fall of Dhayah was to pave the way for the signing of the General Maritime Treaty of 1820, the first of a number of treaties between the British government and the Sheikhs, or rulers, of what would become known as the Trucial Coast.
