Question: The Peckforton Hills  form a significant part of the longer Mid Cheshire Ridge which extends southwards from Frodsham towards Malpas,  large village that used to be what type of town?
Context: Bickerton Hill refers to two low red sandstone hills that form the southern end of the Mid Cheshire Ridge in Cheshire, north-west England.  The high point, Raw Head, lies on the northerly hill and has an elevation of 227 metres.  Parts of the southerly hill are also known as Larkton Hill. Woodhouses hill fort is an Iron Age hillfort between Frodsham and Helsby in Cheshire, England.  It lies at the northern end of the Mid Cheshire Ridge.  Woodhouse Hill has steep cliffs on the western sides, providing a natural defence.  It is defended by a rampart to the north and east where the ground slopes more gently.  Excavations in 1951 showed that the rampart was originally 4m high and revetted with stone on both sides.  A number of small rounded stones, believed to be slingstones, have been found on the site.  The hill fort is protected as a Scheduled Ancient Monument. Malpas is a large village that used to be a market town.  It is also a civil parish in the unitary authority of Cheshire West and Chester and the ceremonial county of Cheshire, England.  The parish lies on the border with Shropshire and Wales.  The name is from Old French and means "bad/poor" ("mal") and "passage/way" ("pas"). The Mid Cheshire Ridge is a range of low sandstone hills which stretch north to south through Cheshire in North West England.  The ridge is discontinuous, with the hills forming two main blocks, north and south of the "Beeston Gap".  The main mass of those to the south are known as the Peckforton Hills; the larger group of hills to the north do not have a collective name. Kelsall is a medium-sized agricultural/commuter village and civil parish in the unitary authority of Cheshire West and Chester and the ceremonial county of Cheshire, England.  It is located around 8 mi east of Chester, 8 mi west of Northwich and 4 mi north west of Tarporley.  The village is situated on Kelsall Hill, a part of the Mid-Cheshire Ridge, the broken line of sandstone hills that divide the west Cheshire Plain from its eastern counterpart.  The ridge includes other hills including Peckforton, Beeston, Frodsham and Helsby. The Peckforton Hills are a sandstone ridge running broadly northeast–southwest in the west of the English county of Cheshire.  They form a significant part of the longer Mid Cheshire Ridge which extends southwards from Frodsham towards Malpas. The Sandstone Trail is a 55 km long-distance walkers' path, following sandstone ridges running north–south from Frodsham in central Cheshire to Whitchurch just over the Shropshire border.  The path was created in 1974 and extended in the 1990s.  Much of the route follows the Mid Cheshire Ridge but in places the trail also passes through the Cheshire Plain, including farmland, woodland and canal towpaths. Peckforton Castle is a Victorian country house built in the style of a medieval castle.  It stands in woodland at the north end of Peckforton Hills 1 mi northwest of the village of Peckforton, Cheshire, England.  It is recorded in the National Heritage List for England as a designated Grade I listed building.  The house was built in the middle of the 19th century as a family home for John Tollemache, a wealthy Cheshire landowner, estate manager, and Member of Parliament.  It was designed by Anthony Salvin in the Gothic style.  During the Second World War it was used as a hostel for physically handicapped children. Delamere is a village and a civil parish in Cheshire West and Chester, England.  It contains nine buildings that are recorded in the National Heritage List for England as designated listed buildings, all of which are listed at Grade II.  This grade is the lowest of the three gradings given to listed buildings and is applied to "buildings of national importance and special interest".  The largest physical features in the parish are Delamere Forest, and part of the Mid Cheshire Ridge.  Running through the parish are the A54 and A556 roads, and the Chester-Manchester railway line.  Other than Delamere Forest, the parish is entirely rural.  The listed buildings in the parish include two churches, a sundial and, on the former turnpike roads, two mileposts and two buildings that originated as toll houses. The Cheshire Plain is a relatively flat expanse of lowland almost entirely within the county of Cheshire in North West England.  It extends from the Mersey Valley in the north to the Shropshire Hills in the south, bounded by the hills of North Wales to the west and the foothills of the Pennines to the north-east.  The Wirral Peninsula lies to the north-west whilst the plain merges with the South Lancashire Plain in the embayment occupied by Manchester to the north.  In detail, the plain comprises two areas with distinct characters, the one to the west of the Mid Cheshire Ridge and the other, larger, part to its east.
