The following is from the Pastscape site:
"The remains of a Neolithic chambered tomb. The visible remains comprise three large sarsen uprights arranged in an H-plan, topped by a substantial capstone. This structure stands at the southeastern end of a mound orientated southeast-northwest and now most clearly visible on air photographs due to prolonged erosion by ploughing. The tallest of the upright stones stands circa 8 feet above the ground, and the capstone measures circa 13 feet by 9 feet. Ordnance Survey field investigation in 1959 recorded the mound as being of elongated oval plan and measuring circa 80 metres long and up to 33 metres across, with an average height of circa 0.7 metres. The flanking ditches can be seen on air photographs as cropmarks. Minor excavation in the late 18th century proved fruitless. Trial trenching of the mound in 1956 confirmed suspicions that the mound had been revetted by a sarsen kerb. While much of the original form of the monument is speculative, even less is known of the contents, the chamber having been open since at least the late 16th century. There are vague mentions of "rude pottery" and some worn sherds said to be Neolithic or Beaker were found in the surrounding ploughsoil in the 1930s. A large sarsen recorded nearby by Stukeley in the 1720s, and known as The General's Tombstone, may have derived from Kit's Coty House. The chamber (but not the mound) was one of the first Scheduled Ancient Monuments, the iron railings surrounding it (erected at the insistence of Lt General Pitt Rivers) testament to early ideas about protecting such sites".
