Durlston Country Park is a 1.13 square kilometre (280-acre) country park and nature reserve stretching along the coast of the Isle of Purbeck at Durlston near Swanage in Dorset, England. The Park, which is part of the Jurassic Coast World Heritage Site, has been owned by Dorset County Council since the early 1970s and is mostly open access.
The Lighthouse is at Anvil Point is built of local stone and was completed in 1881.
The Park has a mosaic of habitats, hosting a wide range of species. Habitats include sea-cliffs, downs, ancient meadows, hedgerows, woodland, and dry-stone walls – each with their characteristic plants and animals. These include 33 species of breeding butterfly, over 250 species of bird recorded, 500 wildflowers, 500 moths and thousands of other invertebrates.
The underlying rock is limestone so the majority of the park is calcareous grassland, probably created about 1000 years ago by clearing of oak forest, hosting a range of wild flower species and associated animals such as butterflies.
In the 19th and 20th centuries Purbeck was quarried for its high-quality limestone. There were few open-cast quarries, and none in Durlston, but there are many mine shafts across the landscape, notably Tilly Whim Caves in a dry glacial meltwater valley.
