The colonial fortress of Batticaloa is a vestige left over from the Portuguese era. It was built in 1628 and was mainly used as a means of protecting the eastern waterways of the countries.
The complex was eventually captured by the subsequent Dutch and British colonisers who used it as a defensive structure, and thereafter as an administrative complex. Even today, certain local government authorities function within the fort.
The four main bastions allow you to gaze at the lagoon and the city from an elevated position. If you get there pretty early in the morning, you would be able to catch a beautiful sunrise.
