The fortress’ plan mirrors the Omani building creativity in the Ya’rubi time that saw significant headway in military strongholds and the presentation of mortar-based fighting. The primary piece of the fortification is huge drum-like pinnacle transcends the ground and has a distance across of 36 metres. The solid groundworks of the post go 30 meters into the ground, and a part of the pinnacle is loaded up with rocks, soil and rubble. The entryways are inches down and the dividers are adjusted and vigorous, intended to endure savage blasts of mortar fire. There are 24 openings overall around the highest point of the pinnacle for mortar fire. Contact Oman Tour For Guide in Nizwa 

Two guns watch the entry to the post which opens into a labyrinth of rooms, high-ceilinged lobbies, entryways, patios, thin flights of stairs and halls. Four cannons stay on the pinnacle’s top, down from an aggregate of 24, which once filled in as the fortification’s principle capability. They gave total 360-degree inclusion of the field around making it practically inconceivable for an unexpected assault on the fortification without inciting an answer from the cannons.One of them has the name of Imam Sultan canister Saif engraved on it. Another, from Boston City, was introduced to the principal Omani diplomat to the United States in 1840. Clusters of cannonballs, deformed with rust and age lie around.
