Maiden Castle

The remains of an Iron Age promontory hill fort, Maiden Castle, are located on the southernmost summit of the southerly hill at an elevation of 212 metres. Maiden Castle dates from around 600 BC and is the most southerly of the seven hill forts in Cheshire. The double line of earth ramparts are still visible, forming a semicircle that encloses an area of 1.3 acres (5,260.9 m²) adjacent to the cliff edge. The enclosure has a single entrance at the east side with inturned defensive banks. Archaeological investigations have shown that both ramparts are strengthened by dry stone

 walling; the inner rampart also has timber strapping. The fort was destroyed by fire in around 400 BC, although the area was probably used as a settlement until the Roman invasion of Britain in the 1st century AD.

The site is well preserved despite quarrying of the area during the 17th to early 20th centuries, as well as military training exercises during the 20th century. The remaining earthworks have been designated a Scheduled Monument, and the site is owned by the National Trust. Since 2009, the trust has been removing trees, scrub and bracken from the site, as the roots damage the earthworks. Animal burrows are another threat, and footpath erosion from visitors is also a problem, as the Sandstone Trail cuts across the earthworks.
There is another Maiden Castle which is an Iron Age hill fort 2.5 kilometres (1.6 mi) south west of Dorchester, in the English county of Dorset.

. The township included half a league (about ¾ mile) of woodland, perhaps located on the hills.

17th–19th century

Copper mining at Bickerton was first recorded in 1696. The mine was owned by the Egerton family of Oulton, with eight miners being employed between 1696 and 1698. There were six shafts, one of which was deepened to 156 feet (47.5 m) in 1807. The mines were worked intermittently until 1906. A rare remnant of this local industry is a disused mine engine house chimney in red sandstone, which stands by the A534 at the foot of the northerly hill near Gallantry Bank. The flue of a pumping engine that was used to drain the mine, it dates from the early 19th century and is a grade-II-listed building. The remains of adjacent mining buildings were still standing in around 1920. The Copper Mine public house at nearby Broxton displays mining equipment and pictures.

Quarrying also took place at various sites on the hills, including Maiden Castle from the 17th century. Sandstone was extracted for building, and sand for use as a scouring agent. An iron rock-splitting wedge dating from the 17th century was found during excavations of Maiden Castle.
Mad Allen's Hole, a cave on the southerly Bickerton Hill, is believed by some to be the location of "Allenscomb's Cave" in which John Harris, "the English Hermit", lived for 46 years in the 18th century. According to a pamphlet of 1809, Harris was a man of property from Handley

, who embraced a hermit's life when his parents refused him permission to marry the woman of his choice. He first inhabited a cave in nearby Carden Park, moving to Allenscomb's Cave in the 1760s. Recent research has, however, cast doubt on the identification of Mad Allen's Hole with Allenscomb's Cave. Unlike the cave in Carden Park, no material dating to the 18th century has been discovered at Bickerton, and the name "Mad Allen's Hole" originated in the late 19th century, when the cave was occupied by an eccentric known as Mad Allen. In the early 19th century, the Bloody Bones caves on the northerly hill were occupied by brigands, who terrorised the surrounding countryside, stealing cheese from local farms and plundering graves, as well as selling sand for cleaning. Seven were captured and executed in around 1834.

The Droppingstone Well, immediately north of the Raw Head summit, bears a plaque dated 1861. A photograph of 1910 shows the well in use by locals.

20th–21st century

With the exception of several areas of farmland and former quarries, the SSSI covers the northmost (Kitty Stone) high point and the Maiden Castle area of the southern high point, together with the intervening col. It also extends over Cuckoo Rock, a lower area to the west of the southern high point, which lies to the south of the hamlet of Brown Knowl. It excludes the southwest of the hill, including part of Hether Wood as well as an area of farmland. A total of 117 hectares (289.1 acre) of the southerly hill, covering 90% of the SSSI, are owned and managed by the National Trust.

The lowland heath habitat (heathland below 300 metres elevation) of Bickerton Hill is considered particularly valuable.

 as in an unfavourable but recovering condition in 2005. Management of the area by the National Trust has aimed, since 1992, to promote heathland regeneration by preventing encroachment by birches, scrub and bracken. Strategies used include bracken rolling, clearing birch scrub and removing some older trees from heathland areas. Grazing with cattle is employed in summer. Tree clearance, has, however, resulted in conflict between the trust and a local residents group, Friends of Bickerton Hill, which organised a protest on the hill in October 2008 against tree felling, especially in the picturesque Cuckoo Rock Valley.

Woodland areas are managed to encourage the development of trees of a wide range of ages by halo thinning around older trees, thinning in denser woodland and planting new trees. Dead wood forms an important habitat and is retained.

Other threats to the site include the high volume of walkers, which has led to footpath erosion, and the inappropriate disposal of dog faeces. Bickerton Hill is included in the Cheshire Biodiversity Action Plan

A total of 13.51 hectares (33.4 acre) of the northerly Bickerton Hill has been designated a geological SSSI for its exposed sandstones, which provide important insight into the conditions present during the Triassic

 period. The SSSI is centred on , and encompasses the hill's western escarpment, stretching from immediately west of Droppingstone Well, through Raw Head and Musket's Hole, and into Tower Wood. The land is owned by the Bolesworth Estate, and is managed for pheasant shooting, with conifer plantation and mixed woodland.

Wilmslow, Bulkeley Hill and Helsby Sandstone formations of the Sherwood Sandstone Group are present within the site, dating from the Early Triassic
Early Triassic
The Early Triassic is the first of three epochs of the Triassic period of the geologic timescale. It spans the time between 251 ± 0.4 Ma and 245 ± 1.5 Ma . Rocks from this epoch are collectively known as the Lower Triassic, which is a unit in chronostratigraphy...

Sedimentation
Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained, and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration...

, runs over the top of the two hills, and there are several other public footpaths and a network of waymarked permissive paths. A total of 8500 walkers on the Sandstone Trail were recorded by the National Trust between January and March 2006, and the trust has estimated that 8000 dog walks occur annually within the Bickerton Hill SSSI. The longer of the two Sandstone Trail Races, organised by Deeside Orienteering Club in early October, goes over the two hills, starting from Duckington and following part of the Sandstone Trail.

Limited access by public road is available to the northerly hill: Coppermine Lane climbs from the A534 to the east of the summit plateau, and New Lane runs from Harthill

Goldford Lane, Old Coach Road, Hall Lane, Brown Knowl Lane and Reading Room Lane run around the southerly hill; Sandy Lane runs from Brown Knowl to the edge of the Cuckoo Rock area. Two free car parks, at (Pool Lane, off Goldford Lane, near Bickerton) and (off Old Coach Road, near Duckington), are open during daylight hours. A small additional parking area for the disabled is located off Goldford Lane ; it requires advance permission. An easy-access footpath suitable for people of limited mobility runs from this parking area to Maiden Castle. The majority of paths have wicket gate
