Nizwa Fort is one of the most popular tourist spots in Oman and is located about 2 hours drive from Muscat city. It was built by Imam Sultan Bin Saif Al Ya'rubi in 1650. However, the foundations of this fortress were built as early as the 12th century. The fort is a great example of Omani architecture during the 17th century. The fort is unique in the shape of its main tower; it is the only one in Oman that is cylindrical in shape. The main tower is also the largest tower in any fort in Oman.
Seven wells and a number of prisons can be found in the fort. The main tower houses a large number of defense mechanisms that have protected Omanis in the past. These mechanisms include various traps or windows from which enemies were shot at.
