The original building dates back to the nineteenth century, although it is not known who ordered its construction. Mezyad Fort is adjacent to a palm plantation and is surrounded on three sides by groves of palm trees. The eastern flank provides a commanding view over a broad plain that would have given the fort’s defenders early warning of any threat from hostile tribes. Mezyad Fort is one of the largest and most heavily fortified buildings in the Al Ain region, occupying an area of around 3,600 square metres, and guarded by high watchtowers at each of its four corners. Machicolations (masonry) projections with a hole in the floor for dropping stones and boiling liquids on the enemy below) and gun openings punctuate the walls at regular intervals. More than forty rooms face inwards onto the large courtyard and would have provided accommodation and storerooms for a sizeable military force. The fort provided a safe haven for local people in times of danger and a centre for communal gatherings.
