Salimgarh Fort (सलीमगढ़ किला)

The Yamuna River Island Fortress: Suri Stronghold to Imperial Prison

Constructed upon a natural island in the channel of the **Yamuna River** in **1546 CE**, **Salimgarh Fort (सलीमगढ़ किला)** is one of Delhi's most historically layered medieval fortifications. Built by **Salim Shah Suri (Islam Shah Suri)**, son and successor of the great Afghan emperor Sher Shah Suri, the fortress was designed as a defensive river citadel to secure Delhi against the anticipated return of Mughal Emperor Humayun from exile in Persia.

When Mughal Emperor **Shah Jahan** constructed the magnificent **Red Fort (Lal Qila)** between 1638 and 1648 CE, Salimgarh Fort was incorporated into the greater imperial palace complex, linked by an arched masonry bridge across the river channel. Under **Emperor Aurangzeb**, the fortress was transformed into a high-security state prison where royal dissidents—including Aurangzeb’s younger brother **Prince Murad Baksh** and his Sufi poet daughter **Princess Zeb-un-Nisa**—were held in solitary confinement. During the Indian Independence Movement, the British used Salimgarh's brick barracks to imprison officers of Netaji Subhas Chandra Bose’s **Indian National Army (INA)** during the historic 1945 Red Fort Trials.
