Introduction to Khan Jahan Ali Kortik Khononkrito Boro Dighi-
Khan Jahan Ali Kortik Khononkrito Boro Dighi is one of the largest and most historically significant water reservoirs in the Bagerhat District of Bangladesh. Situated adjacent to the famous Khan Jahan Ali’s Shrine in Bagerhat, this enormous tank stands as a testament to the advanced civil engineering and water management practices introduced by the revered Muslim saint and administrator, Khan Jahan Ali, in the 15th century. The term “Boro Dighi” literally translates to “Large Tank,” and its utility, size, and architectural harmony with the nearby structures make it a vital heritage site in the region.
Historical Background-
The Khan Jahan Ali Kortik Khononkrito Boro Dighi was excavated during the reign of Sultan Nasiruddin Mahmud Shah of the Bengal Sultanate. Khan Jahan Ali, a renowned saint and administrator, was responsible for urbanizing the area of Bagerhat, then known as Khalifatabad. He constructed mosques, roads, bridges, and water tanks to develop the area as an Islamic township. The Boro Dighi was one such public infrastructure aimed at providing fresh water to the community for daily use, religious ablutions, and agriculture.
The excavation of Boro Dighi is attributed solely to Khan Jahan Ali’s leadership. Historical records suggest that the tank served thousands of people and was a model for other water conservation projects in medieval Bengal. The tank’s presence beside the Khan Jahan Ali Mazar (shrine) adds to its spiritual significance.
Architectural Features-
The Boro Dighi is rectangular in shape and spreads across a vast area, believed to be approximately 1,320 feet in length and 600 feet in width. The banks of the tank are meticulously sloped and stabilized using laterite stones and bricks—an architectural style common in the structures built under Khan Jahan Ali’s direction.
A distinctive feature of the Boro Dighi is its symmetry and the harmony it maintains with the surrounding religious monuments, such as the Sixty Dome Mosque (Shat Gombuj Masjid) and the Nine Dome Mosque. The water body not only served a utilitarian purpose but was also part of the landscape design of the medieval Islamic township.
The tank’s water still remains fresh and is considered sacred by many visitors and devotees who come to pay respects at the nearby shrine. Fish and turtles inhabit the waters, and the tank contributes to the ecological balance of the area.
