Mam Tor is a 517 m high mountain northwest of Castleton in Derbyshire in England . The Hillfort at the summit is the only large hill in the Peak District that has been excavated.
On the Mam Tor there was initially a hill fort or a place protected by a palisade and moat, which developed into a hill settlement with heavily fortified entrances. On the summit, however, the remains of two early Bronze Age burial mounds were discovered that are older than the Hillfort. The hill is crowned by a simply walled hill fort from the late Bronze and early Iron Ages . The tongue-shaped earthworks, which are still visible around most of the hill, enclose an area of around 5.0 hectares and consist of a wall, an outer ditch and another wall, which may have been created when the ditch was cleaned. The traces of the two entrances can be seen on the trails that lead from Mam Nick and Hollins Cross to the southwest and north.
At the foot of the gate or near it are four show caves : Blue John Cavern, Speedwell Cavern, Peak Cavern and Treak Cliff Cavern, where lead , the mineral Derbyshire Spar (Blue John), fluorspar and other minerals were once mined.
Mam Tor is made up of rocks from the Carboniferous Period, around 320 million years old . The base consists of black slates from the Serpukhovian , overlaid by sandstone formations from the Bashkirian .
The name Mam Tor means "mother hill" because landslides on its eastern flank led to a large number of "mini hills". The landslides caused by unstable shale layers gave the hill its alternative name Shivering Mountain. In 1979 the battle to maintain the A625 (Sheffield - Chapel en le Frith) road on the east side of the hill was lost when the road officially closed.
