There is a scheduled ancient monument no.13522, Coatestown Bowl Barrow, to the SW of the village. There is very little to see but it is listed as Bronze Age. It was scheduled on the 1st of November 1966 by the Ministry of Public Works and Buildings. A document from English Heritage in 1992 says that it was excavated during the 19th century by Jewitt and Lucas, finding human cremations and charcoal and burnt flints. The details are now in Staffordshire County Council Historic Environment Record.
The following extract is taken from the The Reliquary and Illustrated Archaeologist,
Opening of Grave Mounds in the Peaks by John F Lucas and Llewellyn Jewitt, 1862
Hollinsclough.—On the 17th of November, we proceeded to open a low mound on the Staffordshire side of the river Dove, on a heathy enclosure at the top of a steep hill, known by the not very euphonious name of " Bitch-hole," above the quiet and unpretending little village of Hollinsclough. The mound is about thirty-six feet across, and raised about three feet above the surface of the hill. It was sunk in the centre, and thickly covered with heath and bilberry-wires. The accompanying plan will show the exteut of our operations. Our first opening was a trench running nearly east and west, and widened in the centre of the barrow. At A we were fortunate in discovering, at a depth.of three feet, an interment of partially burnt bones, with fragments of charcoal, and half of a very fine spear-head of burnt flint, and some other flakes of flint. The remains were those of an adult, but wefe very fragmentary, one side of the lower jaw, with the teeth, and some of the vertebrae, being the most perfect. In other parts of this opening, appearances of burnt stones and layers of burnt earth were observed. The heap of ashes and bones lay in a hollow in the natural surface of the hill, and were surrounded and covered with small stones.
Our next opening was made as shown at F. At B was a similar interment, with much charcoal mixed with the ashes. A remarkably good burnt flint, thick, and sharpened at the rounded end, as if for chipping with, was found, as were also some other fragments of calcined flint. The deposit was that of a young person, and was placed on the old ground, two feet six inches below the present surface. At D was a layer of charcoal, and above it the very nice little arrow-head shown in the accompanying engraving. Another opening was then made at C to the depth of about two feet six inches, when the same bed of charcoal, mixed with white sand, was come to, and there were also, here, traces of human ashes and burnt stone.
It is worthy of remark, that some of the fragments of charcoal found in this barrow were of large size, and were evidently formed from wood some inches in diameter, and not from twigs as is usually the case.
