Dr Clive Waddington and the Longstone Local History Group, excavated Fin Cop in July 2009, several open days for public viewing were held...
"It is believed the Iron Age hillfort is between 3,000 and 2,000 years old. Radiocarbon dating of surviving material is likely to enable more accurate dating... continues...
It's a fabulous place. The path up to the enclosure was called Pennyunk / Penyonke [Lane] back to the 1300s and likely long before[http://www.geograph.org.uk/photo/351089] as this seems to be a pre-English [i.e. Old Welsh] name [it doesn't make any sense in Old English but does in the language spoken in the Peak until the 7th/8th C]. Pennyunk would have meant something like 'headland of [the] youth' in Old Welsh [Pen = top, end, head, headland; Iouanc = youth, youngster]. It's possible that this was the pre-English, P-Celtic, name for the enclosure. After all, Penbroga [= 'land's end' = Pembroke] goes back to the Iron Age... Cf. the shape of the hill with another 'penn'; Pendle.
The fort at Fin Cop is an easy walk from the Monsal Dale Hotel, with some excellent views of Monsal Dale below on the trek out.
The fort is defended to the South and East by banks and ditches and to the North and West by the steep sides of Monsal Dale. At the Eastern side, the side you approach from, double banks and ditches are still impressive, an entrance is central to this part of the defences, which carry on over the wall in the form of a single bank.
The views from the top are unreal with Five Wells in the West, Kinder Scout just visible in the North and Beeley Moor quite close in the South-East(ish).
Monsal is one of the best places to watch a Derbyshire sunset without doubt.
An added attraction this time of the year are the banks of the fort covered in Mountain Pansies and 'Early Purple' Orchids.
I guess we will only ever be able to speculate about what this could have meant:
In the year 1795, two kistvaens, or British sepulchres, were discovered by Major Rooke, on opening a large tumulus upon Fin-cop, about two miles north-west from Ashford.
In one of these was a skeleton, with the face downwards, having a piece of the black Derbyshire marble, two feet long, nine inches wide, and six inches thick, lying on the skull; under the head were two arrow-heads of flint..
[also] a small, flat, circular stone, which had a thin body of stucco on both sides; the top, which was of a yellowish colour, had apparently been varnished.
Elsewhere urns, burnt bones and ashes were found, and a spear-head of stone. From 'Vestiges of the Antiquities of Derbyshire' by Thomas Bateman (p26. published 1848). You can see it at Google Books.
W. Storrs Fox excavated the cave in 1911, well sent a couple of local lads into the fissure, they recovered the bones of a subadult(?) and Bronze Age pottery.
The fissure cave on the tumbled limestone rocks of Hob's House, on the northern side of Fin Cop, was once said to be the home of the giant Hulac Warren (sometimes Hector Warren) or Hob.
On a bend in the river, closer to Demons Dale, stands the Warren Stone. Which is said to be the petrified remains of the giant who was turned to stone for the attempted rape of a shepherdess. During the attack she either fell or threw herself to her death. Where her body landed a spring of pure water formed.
In an old local rhyme suggesting witchcraft in the area, Hob is portrayed as a fiddler:
The piper of Shacklow,
The fiddler of Fin,
The old woman of Demons Dale,
Calls them all in.
