Looking north to Mam Tor. The line of defenses can be seen as the narrow light band below the summit.
The mighty hill of Mam Tor
(sometimes known as the Shivering Mountain because of landslides on it's
eastern side) stands at the western end of the Hope valley above Castleton
with the Vale of Edale just to the north and offers as fine a view of
the surrounding landscape as just about any site you could find. The first
evidence of prehistoric use of the hill comes from the Bronze Age but
it must have been a significant place to people long before that - indeed
a polished stone axe and flints from the Neolithic had been found here.
The first Bronze Age remains at the site consist of 2 round barrows near
the top of the hill - one actually has a trig point that records the height
as 517 metres above sea level. This particular barrow is quite low and
is now cobbled to protect it from damage but the other barrow to the southwest
is quite well preserved despite having a large crater-like hole in it's
top. Both barrows have fine views to the north, south and west.
During the later Bronze Age and into the Iron Age the hill was occupied
as a ''slight univallate hillfort'' which is defined as a small hilltop
enclosure consisting of a single line of defenses. Mam Tor fits this description
in that it's earthwork is a single rampart, a berm, a ditch and an outer
bank that enclose an area of about 6 hectares near the top of the hill.
It is thought that the rampart was originally built as a wooden palisade
cut into the hillside before being replaced by a more sturdy stone defense
that could have been as much as 3 metres high and 5.5 metres wide on the
eastern side. Next there is a flat terrace (or berm) then a U shaped ditch
which is now silted up but which could have been up to 2 metres deep and
about 2.5 metres wide. Finally a small outer bank would have been around
1 metre high and 2 metres wide. The site was entered by interned entrances
to the north and the southwest, this second one being better preserved.
Within the internal area of the enclosure, and on either side of the main
ridge of the hill, were found the remains over 70 hut platforms which
were built by first cutting a level surface into the side of the hill
before constructing turf or stone walls and internal hearths and pits.
Excavations around and inside these huts revealed much broken pottery
as well as whetstones and shale beads.
