Ramsagar National Park is built around a large man-made tank south of Dinajpur. The water body dates to the 18th century and was dug under a local ruler, turning a practical reservoir into the kind of landscape feature that still shapes a day out.
It is a calm counterpoint to the temples and palace ruins. Visit for a walk, shade, water views, and a sense of how old public works can become part of a town's memory.
