Fort Vijf Sinnen (also Vyf Sinnen, Dutch for "the five senses") was a fortification made by the Dutch East India Company in Nagapattinam, then part of Dutch Coromandel (1610-1798), now Tamil Nadu. The fortification, also described as a castle, was built to protect the interests of the trading company, which shifted the capital of the Coromandel operation from Pulicat to Nagapattinam in 1690, three years after work began on the fort.
