Kot Diji Fort - Construction

Construction

Kot Diji is a very practical fort constructed on a limestone hill with kiln-baked bricks. Bricks were used because the locally available limestone rock was very brittle and would have shattered easily on impact with a cannonball. The hill is about 110 feet high, above which the walls of the fort rise another 30 feet. It has three strategically placed towers about 50 feet tall.

The fort is over half a kilometer long. Its walls are segmented by about 50 bastions, and its 1.8 km outer perimeter wall identically follows the double crescent-shaped contours of the hill it stands on. This allows the fort to surround the attacking enemy on three sides on the west front. On the east, where the entrance lies, the fort is divided by three elephant-proof gates into three overlapping levels, so that the first two levels can be attacked by the next level above them in the event of the lower level being overrun by the enemy. The first gate is not a prominent portal but rather an indirect entry so that the gate cannot be rammed on a charge. The walls and bastions have arrow slits in them, allowing defenders to attack their enemy from two levels: from the battlement on top and from within the wall.

The fort was built at a time when cannons had become common and its design and position reveals that. It includes a multitude of stations for cannons and, because it is positioned high on a narrow ridge, enemy cannons would have had to fire at a great distance, permitting little accuracy. Cannonballs could either hit the hill or perimeter or would simply fly over the fort and fall on the enemies' own forces on the other side.
