Overbury's Folly is a seashore recreational park in Thalassery, located on a hill near the Thalassery municipal stadium. The park is named after E. N. Overbury, the British Sub-Collector who constructed this park in 1879. However as he was unable to complete it, the park earned the name Overbury's Folly.
The park, which slopes down from the Sub-Collector's bungalow to the rocks below, provides a grand view of the Arabian Sea.
