[1] Credenhill village has had military connections since 80 BC, when Iron Age Celts constructed a hill fort and earthwork defence system commanding the surrounding area.
During the First World War, land in Credenhill was occupied by an army unit to store ammunition.
Original in-turned entrances are at the centre of the east side and at the south-east corner, each approached by a hollow way cut deeply into the hillside.
Its gradual in-filling was found to include various occupation layers associated with rectangular wooden buildings with four corner posts, measuring about 12 x 8 ft (2.4 m), which had been rebuilt several times in the same place.
There were also storage pits and other remains of occupation including pottery with stamped and incised patterns typical of the West Midlands Iron Age.
It was redeveloped by the British Army for new headquarters for the 22 Special Air Service Regiment, who moved out in 1999.
In contrast, the minimum temperature on 26 December 2015 was 12.9 °C (55.2 °F), higher than even the average July night, the warmest month of the year.
