Fort Dansborg, locally called Danish Fort, is a Danish fort located in the shores of Bay of Bengal in Tranquebar in the South Indian state of Tamil Nadu. Fort Dansborg was built in the land ceded by Thanjavur king Ragunatha Nayak in an agreement with Danish Admiral Ove Gjedde in 1620 and acted as the base for Danish settlement in the region during the early 17th century. The fort is the second largest Danish fort after Kronborg. The fort was sold to the British in 1845 and along with Tranquebar, the fort lost its significance as the town was not an active trading post for the British. After India's independence in 1947, the fort was used as an inspection bungalow by the state government till 1978 when the Department of Archaeology, Government of Tamil Nadu took over the control of the fort. The fort is now used as a museum where the major artifacts of the fort and the Danish empire are displayed.
