In 1700, the British built the Thalassery Fort on a small hill called Tiruvellapadkunnu. The fort is a square structure built of laterite and is distinguished by its massive ventilated walls and strong flanking bastions. It is said that a mixture of quicklime, white of egg and sugar candy were used in the construction of the fort. It was here that Raider captain was imprisoned. The famous St. John's Anglican Church is behind this fort. Secret tunnels to the sea, beautifully craved doors and a beaming light house are some of the peculiarities of the Fort. There are two underground chambers in the light house that were believed to be used to store goods like pepper and cardamom. It is said that the coins of the East India Company were minted here.
