[1] [2] East Pit is part of the Cherry Hinton Pit biological Site of Special Scientific Interest, which excludes Limekiln Close but includes the neighbouring West Pit. [3] [4] The two parts of the site are both former chalk quarries. East Pit is surrounded by steep walls of chalk, and the base is wildflower grassland with areas of scrub.
Burning chalk stone was performed in simple kilns in close proximity to where the chalk was found. Lime kilns were made by digging a round hole, three metres wide, two and a half metres deep. After the hole was dug, the chalk and fuel for a fire would be brought to it. Stones of chalk (limestone) would be arranged in a circular dome in the pit.
The oak woodland is ancient, and it provides a feeding habitat for the bats. [1] The deneholes in the wood, which were sometimes known as Cunobeline's gold mines, [7] are described by English Heritage as medieval or post-medieval and were used for chalk or flint mining. [8] The origin of these deneholes is discussed by Tony Benton. [5]
The caves were used between 1830 and the 1860s for producing lime. The 25-inch to a mile (approx 1:2,500) Ordnance Survey map of 1862–63 describes the place as a "chalk pit" and marks an "engine house" and two remaining kilns. [9] A further investigation produced, among other evidence, a letter from the son of one of the workers. [10]
