Cranganore Fort, otherwise known as Kodungallur Fort is situated in Kodungallur of Thrissur District in Kerala. It was built by the Portuguese in 1523 A.D. and was called Fortaleza da Sao Tome. The Dutch took possession of it in 1661 and later it came under the control of Tipu Sultan. The Dutch wrested it back from Tipu Sultan, but the fort eventually came under the control of Tipu, who destroyed it in the following year. The remains of the fort show that the original fort wall was 18 feet in thickness. The ruin is also known as Tipu’s fort. The fort is about 2 km from the town of Kodungallur.
