The castle, originally owned by the d'Umfraville family, then the Percys and now English Heritage, is considered to be the only medieval fortification in Northumberland never to have been captured by the Scots.

In 1914, a Territorial Army drill hall was developed on Swalwell Close, which housed a company of the 4th Battalion of the Northumberland Fusiliers.

[4] The drill hall site (now disused) was scheduled to be redeveloped from 2018,[5][6] with the scheme further delayed and complicated by the jailing of the owner for eight years in 2021.

[7] During the Cold War, there was a Royal Observer Corps Underground Monitoring Post opposite Highfield Park; the surface features have since been demolished.

Prudhoe ROC post was opened in June 1962 and closed in September 1991 after the collapse of the Soviet Union, which saw the end of the Cold War.

Electorally, the town is located within the parliamentary constituency of Hexham and is therefore represented by Joe Morris of the Labour Party in the House of Commons.

The civil parish borders Tyne and Wear (as well as historic County Durham) over Stanley Burn in the east of town.

There is still evidence of the old coal mine at West Wylam, signified by a miner's cart when driving into Castlefields up Cockshot Dean.

[citation needed] In 1963 this plant closed leaving behind the "Spetchells" chalk hills – heaps of waste product which were subsequently turfed over.

After ICI closed, the site was owned by Cleveland Engineering, which produced automobile parts,[citation needed] and following its closure in 1969 Kimberly-Clark opened.

It was built by the d'Umfraville family: the Norman Sir Robert de Umfraville was granted the freedom of Redesdale by William the Conqueror.

[11] The majority of the surviving building work dates from the 12th century, although the site of Prudhoe Castle has strong Norman origins.

This means that the Cottier windows have been moved twice from their original site, and this would explain the necessity for so much extra remedial lead-work within some of the panes of glass, presumably repairing damage caused by two removals and two re-installations.

The small windows at Prudhoe Hall depicting idyllic naturalistic scenes of a rising sun over a river are especially beautiful, and seem to have a strong similarity to the work of Louis Comfort Tiffany.

The better transport links of the new bypass have allowed the industrial estate to expand alongside the new road to the east, named Princess Way after the royal who opened SCA Hygiene.

Northumberland County Council sought a significant landmark feature adjacent to the new bypass, and commissioned the Prudhoe Badger under their 'percent for art' policy.

It was designed to integrate with the rural environment, create awareness about ecology and provide a link with the nearby Countryside Centre.

The park includes the artificial chalk hills known as the "Spetchells" which have attracted some natural chalk-loving flora and fauna not normally found in the region.
