The 18th century construction of Ghayl Fort was commenced by Ali Bin Zahi in 1800 but completed by Sheikh Saeed bin Hamad Al Qasimi, the Al Qasimi wali of Kalba. Four and a half kilometres inland of Kalba, the fort has a commanding view of the lower reaches of the Wadi Helo. The entrance to the fort faces West and it has a prominent four-story watchtower to the North. With an inner area of 15 x 20 metres, the fort was reduced once again to the role of watchtower in the 20th century before being restored. Saeed bin Hamad Al Qasimi also maintained a seaside house in Kalba.
