Alton Castle is a Gothic-revival castle, located on a hill above the Churnet Valley, in the village of Alton, Staffordshire. The site has been fortified since Saxon times, with the original castle dating from the 12th-century. The current castle was constructed in the mid-19th-century by John Talbot, 16th Earl of Shrewsbury, of near by Alton Towers. Since 1967 the castle has been designated a Grade I listed building. It is also a scheduled ancient monument.
Alton Castle was founded by Bertram de Verdon and built on a rocky precipice overlooking the River Churnet in the 12th century,, however the site had been fortified since Saxon times. The castle is also known as or referred to in historical documents as Alton, Alverton or Aulton. The 12th-century castle was substantially reconstructed during the 15th century and subsequently was damaged during the Civil War.
Since 1442, the castle was in the possession of the Earls of Shrewsbury, who from the beginning of the 19th-century made their home at nearby Alton Towers. By the mid-19th-Century the castle was mostly in ruins. John Talbot, 16th Earl of Shrewsbury, commissioned Catholic architect Augustus Pugin, who was already working for the Earl at Alton Towers, to construct a new gothic castle/country house on the site. Most of the 12th-century ruins were demolished to make way for the new building which was designed to look like a French or German medieval castle. The earl also commissioned Pugin to develop the surrounding area on castle hill. A "replica of a medieval hospital, a guildhall and presbytery" were constructed; dedicated to St. John the Baptist, the buildings served as a church and hospital (almshouses) and were designed to provide and care for the poor for of the parish. The church was also used as a school for local poor children.
It is unclear why the 16th Earl had the castle rebuilt. It may have been intended for the Earl's cousin and eventual successor, Bertram Talbot (17th Earl of Shrewsbury); or it may have been intended as a Dower House for the Earl's wife, if he should predecease her. Towards the end of the castle's construction, the earl suggested the castle could be a home for priests, but Pugin was "vehemently against the idea".
The site was taken over by the Sisters of Mercy in 1855 and the presbytery became their convent. The castle remained a private residence until 1919 when the Sisters of Mercy bought it for £3,500 to extend their boarding school. The school closed in 1989 and the castle was left empty until in 1996.
Alton Castle is now in its 15th year as a residential youth centre and UK registered charity working with children aged between 9 and 13 years. Over 8,000 children visit the Castle each year, mainly with schools, but also from other children’s organisations such as youth groups and charities who work with children with disabilities. Some of the children have suffered disadvantages, including disability, and many come from inner city areas of social and economic deprivation.
Alton Castle aims to raise self-esteem, to strengthen and build friendships, and to help each child realise their potential as human beings. The children participate in a variety of activities during their stay including mountain biking, trekking, archery, rockclimbing and survival.
