Ranikot

An enormous fortification built on barren hills in the extreme north-eastern part of the park. Ranikot is believed to be one of the largest forts in the world and is a major attraction in the region due to its mind boggling size: the fort’s massive 10-m-high walls of dressed sandstone are 26 km in circumference. Seen from a distance, portions of its ramparts resemble the Great Wall of China, as they dip and turn to the contours of the hills. It was built for bow-and-arrow warfare but it was later enlarged to withstand and cope with firearms. Some attribute its construction to Arabs and some to the then-Persian Governor of Sindh in 836 AD and yet other Sindh archaeologists think that some of the present structure, and especially a small inner fortress about 8 km inside the main gate, was either constructed or renovated in the early 19th century by Talpurs of Sindh. Reasons for its baffling construction in this desolate area are equally diverse and unsettled.
The fort’s structure, encircling many hills is long, strong walls are made of gypsum and lime-cut sandstone.
