The Old Fort of Surat was originally built in the 14th century by Muhammad bin Tughluq of the Delhi Sultanate. It was later rebuilt and fortified by the Portuguese in the 16th century. In the 17th century, the fort came under the control of the Mughals, who further strengthened its defenses. During the British colonial era, the fort served various purposes, including a prison and administrative center. The fort has witnessed numerous battles and sieges, making it a significant historical site. Today, it stands as a testament to Surat's resilience and its role in the region's history.
