Blue Pool is a flooded, disused clay pit where Purbeck ball clay was once extracted. It is now a lake within the Furzebrook Estate, a 25-acre (10 ha) park of heath woodland and gorse near Furzebrook on the Isle of Purbeck, in the county of Dorset, southern England.Furzebrook Estate is about 3 mi (5 km) south of Wareham and 2 mi (3 km) west of Corfe Castle. The pool started life early in the 17th century as a chalk pit. Purbeck ball clay was dug from the pit from the mid-17th century to the early 20th century. The ball clay was used to make fine ceramic products, such as smoking pipes, plates, cups and tea pots. The pit became disused before the First World War, but ball clay is still extracted from other pits in the area. The title 'blue' arose because there are minute particles of clay in colloidal suspension within the water. These suspensions variously diffract the light depending on the particles' size (with differences in size often linked to changes in concentration and pH), yielding colours from red-brown, through grey and green, to the more typical turquoise. The metallic blue sometimes found in photographs is more likely to be a reflection of the sky, as the attraction's own website makes no such claim for the water, and their leaflets call it “a turquoise jewel set in the heart of Purbeck”. In 1935 a café was opened at the site. There is also a museum and gift shop. In 1985 the estate was declared a Site of Special Scientific Interest. Now law protects the habitat of a variety of rare plants and animals. The site includes nature reserves managed by the Amphibian and Reptile Conservation and a private nature reserve. Blue Pool is now a popular tourist attraction, especially because it is a place of peace and tranquillity. The pool is surrounded by 25 acres (10 ha) of heathland. The nationally rare Dorset heath and marsh gentian are common to the area. The estate is crossed by a network of sandy paths. There are steps down to the edge of the pool and there are also steps on some paths around the pool, but there is also a completely flat route around the pool, which is suitable for wheelchairs. The lush vegetation around the pool is inhabited by grey squirrels, rabbits and badgers. The Estate supports numerous rare birds, amphibians and reptiles. Visitors may therefore be lucky enough to spot the Dartford warbler or the nightjar. Both of Britain's endangered and protected reptiles, the green sand lizard and the smooth snake, live here in considerable numbers. There are also many dragonflies and the rare Sika deer.

Purbeck Hills
Purbeck Hills

The Purbeck Hills, also called the Purbeck Ridge or simply the Purbecks, are a ridge of chalk downs in Dorset, England. It is formed by the structure known as the Purbeck Monocline. The ridge extends from Lulworth Cove in the west to Old Harry Rocks in the east, where it meets the sea. The hills are part of a system of chalk downlands in southern England formed from the Chalk Group which also includes Salisbury Plain and the South Downs. For most of their length the chalk of the Purbeck Hills is protected from coastal erosion by a band of resistant Portland limestone. Where this band ends, at Durlston Head, the clay and chalk behind has been eroded, creating Poole Bay and the Solent. The ridge of steeply dipping chalk that forms the Purbeck Hills continues further east on the Isle of Wight. The height of the chalk ridge and proximity to Poole Harbour and the south coast have made the hills of strategic importance. There are a number of Iron Age, Roman and Saxon archaeological sites, such as Nine Barrow Down. At Corfe Castle the hills are broken twice leaving a steep round hill between the ridges on which stood a medieval castle, guarding the only easy route through the hills, until the English Civil War of the 17th century, when it was slighted. Some of the ridge, around the village of Tyneham, near Lulworth, has been closed to the public for use by the army as a firing range. This has protected them from damage from farming and development, and these areas are now nature reserves. At the eastern end Ballard Down is a National Trust nature reserve which is managed for its calcareous grassland habitat.
