The Portuguese Cemetery (after the invasion of Dutch, it became Dutch Cemetery) of Tangasseri in Kollam city, India, was constructed around 1519 as part of the Portuguese invasion of the city.

[3] The remnants of St. Thomas Fort and Portuguese Cemetery still exist at Tangasseri.

Popularly known as Tangy, Tanganeri was an erstwhile trading outpost of the Portuguese, other Europeans, Arabs, Chinese and Jews.

[4] The site is a centrally protected monument under the control of Archaeological Survey of India since 1920.

There is some unconfirmed news that the authorities are not protecting these remnants well and some apartment constructions have already started there at this heritage site.
