Tilly Whim Caves consists of three stone quarries in Durlston Country Park, 1 mile (1.6 km) south of Swanage, on the Isle of Purbeck, in Dorset, southern England.

Using only metal punches, wedges and hammers to split the rock into workable blocks, the quarrymen mined the stone horizontally out of the cliff face.

Using a "whim", a special type of wooden crane, the finished stonework was lowered from the quarry ledges to the boats below.

[3] Purbeck stone was used extensively during the Napoleonic wars for building fortifications along the entire south coast of England.

The area surrounding Tilly Whim is also a look out point for marine life, including grey seals and dolphins.
