Sharjah Fort (Al Hisn Sharjah) is a double story traditional rock, coral and adobe fortification in the centre of the city of Sharjah in the United Arab Emirates (UAE).
The fort was originally constructed in 1820 by the then Ruler of Sharjah, Sheikh Sultan bin Saqr Al Qasimi, following his accession to the 1820 General Maritime Treaty with the British. It was partially demolished in January 1970, the one remaining tower (called 'Kubs', that to the far right of the fort) lending its name to the square in which it sits, 'Al Burj', Arabic for 'tower'.
