Ranikot Fort (Sindhi: رني ڪوٽ قلعو‎; also known as Rannikot), also known as the Great Wall of Sindh (Sindhi: سنڌ جي عظيم ديوار‎), is a 19th-century (reconstructed) Talpur-era fort near Sann in Jamshoro District, Sindh, Pakistan.

[4] The fort is listed as a historical site under the Antiquities Act, 1975 and its subsequent amendments, and has a protected status.

A diversion road, starting a little distance away from Sann, the nearest town, leads to the fort along a rugged 21 kilometres (13 mi) road and reaches the eastern gate of the fort, known as Sann Gate.

[11] The battlements of Ranikot formed the last capital of the Amirs of Sind, when they were brought under the colonial rule of the British Empire.

These tests have confirmed that this gate was probably renovated between the early part of the 18th century and the early part of the 19th century, prior to Britain invading the fort when the Kalhoras, or most likely the Talpur Mirs of Sindh ruled over the area.

The fort is huge, connecting several bleak mountains[4] of the Kirthar hills[3] along contours, and measures 31 kilometres (19 mi) in length.

[7] The Fort was first restored by Nawab Wali Muhammed Leghari, who was the Prime Minister of Sindh under the Talpur dynasty.
