Rustaq Fort

Is amongst the oldest, is the tallest, and is surrounded by watch towers. (Al Batinah) originally known as Qalat Al Kisra, was built in the 13th century. It has four towers: Al Burj Al Ahmar; Al Burj Al Hadeeth; Al Burj Al Reeh; and Al Burj Ashiateen (which means, ominously, the devil's tower). A falaj ran through the fort to supply water to its inhabitants. Should this become contaminated, the inhabitants were able to rely on a well. There are many rooms to this fort and it also boasts a mosque, weapons' room, prison, and reception area.
