Tilly Whim Caves

Tilly Whim Caves are three interconnected chambers carved into limestone cliffs with square-shaped openings and flat rock shelves that sit directly above the sea at Swanage. The site lies within Durlston Country Park and displays the typical structure of former stone quarry operations.

The caves developed as limestone quarries during the 18th century, supplying materials for defensive fortifications along England's south coast during the Napoleonic Wars. This connection to military supplies made the site an important economic hub for the region at that time.

The name honours quarryman George Tilly and the wooden crane system called whim that hoisted stone blocks from the cliffs to boats below. This naming tradition reflects how local people remembered the workers and tools that shaped this coastal site.

Access inside the caves has been closed since 1976 due to dangerous rock falls, but you can view the entrances from designated viewpoints in Durlston Country Park. The best time to visit is during clear weather when the cliffs are dry and safe to walk along.

The abandoned quarry tunnels now serve as protected habitats for bat colonies and nesting sites for various seabird species throughout the year. This unexpected transformation from a work site to a wildlife refuge shows how nature reclaims these human-made spaces.
