Marley Hill is a former colliery village about six miles to the south west of Gateshead, near the border between Tyne and Wear and County Durham. It has been part of the Metropolitan Borough of Gateshead since 1974. Prior to this it was part of Whickham Urban District. It lies within the Whickham South & Sunniside electoral ward of the Blaydon parliamentary constituency. Neighbouring towns and villages include Burnopfield (2 miles away); Sunniside, Gateshead (about half a mile away); Byermoor (just under a mile away). Marley Hill, Sunniside, Burnopfield and Byermoor all share Whickham's "NE16" postcode prefix, despite Burnopfield sitting just over the border in County Durham. The actual area considered to be Marley Hill for postal purposes etc. is actually much larger than it would first appear, as there were originally more houses to the south and south east, nearer the colliery. Birkheads Cottages and Hedley Hall Farm are the farthest properties away from the village itself, these being about a mile to the south-east. Hedley Hall Farm's address is anomalously listed as "Hedley Lane, Sunniside", despite actually being further away from Sunniside than Birkheads Cottages, whose addresses read "Birkheads Lane, Marley Hill".
The village consists of several rows of terraced houses, along with a number of detached and semi-detached properties. The oldest existing properties are the former vicarage, the school house, three large detached houses on St. Cuthbert's Road, two stone-built cottages (accessed by a lane leading off to the north-east from St. Cuthbert's Road) and the five rows of houses which form Glamis Terrace, Cuthbert Street and Church Street. The majority of the properties on Cuthbert Street and Church street were built as two up-two downs, and at one time had outside toilets and tin baths which would have been placed in front of the fire. At some point the houses were modernised and had indoor bathroom/toilets installed. Some of the outside toilets with their adjoining coal houses remain, but a number have been demolished, or have had the toilet removed and are used as sheds. The houses on Glamis Terrace were intended for colliery officials, and are therefore fewer in number and considerably larger than the others, with gardens at both the front and rear. It is named Glamis because the Bowes-Lyons, the Earls of Strathmore, who were ancestors of the Queen (Glamis Castle was the childhood home of the Queen Mother) owned the colliery and the surrounding land, including the Gibside estate. Church Street and Cuthbert Street are named after St. Cuthbert's Church, which stands at the corner of St. Cuthbert's Road, opposite the former Miners Welfare Institute (now a community centre housing a nursery and a performing arts school) and the aged miner's cottages.
