History
Foundation
The school owes its existence to the charitable donations of William Jones, who died in 1615. He bequeathed money to the Worshipful Company of Haberdashers for the foundation of a grammar school in Monmouth. An accumulation of funds by the end of the nineteenth century encouraged Monmouth School to build a sister school to serve western Monmouthshire.
Grammar school
After much discussion and debate the town of Pontypool was chosen after land of six acres was donated by local landowner John Capel Hanbury. In 1896 the foundation stone of what was then known as Jones' West Monmouth School was laid by Louisa Eager, wife of John Hanbury. The school was officially opened by Godfrey Morgan, 1st Viscount Tredegar in 1898, to accommodate 70 boarders and 30 day boys. The total cost of erecting the school was estimated at £30,000. The school became a county grammar school in 1954, and the last boarders left in 1958.
Comprehensive
In 1982 the school lost its grammar school status to become a comprehensive school when amalgamated with the three local secondary modern schools at Twmpath, Trevethin and the Wern. A new block was constructed and now houses the mathematics, technology and some humanities classrooms. A new music and performing arts centre was built on the site of the old swimming pool in 2001 which gave the school some of the best facilities in Torfaen.
Expansion and changes of school buildings
The school's original building with its tall spires and grand entrance became too small for the school numbers. By 1934 a new 'Science Block' building had been added at a cost of £20,000 and contained extra classrooms and modern laboratories. The school recently went through a six million pound overhaul that has seen numerous changes. The school now has performing arts facilities including an auditorium housed in the Haberdashers' Building. The special educational needs department has been expanded and there is a new cafeteria.
Facilities
West Mon has an AstroTurf football pitch which comes complete with floodlights. As of November 2019, they have closed the AstroTurf due to it being upgraded to a 4G pitch which will come with new flood lights and fence, construction is due to finish in early April 2020. There is also a performing arts centre and two large gymnasia. There are six IT suites and a comprehensive technology centre. The school also boasts a running track, tennis courts and the large Albion rugby fields nearby. The school has been extended once again; the old dining hall has been converted into classrooms and a new cafeteria built on the west side of the site. This is due to the amalgamation of Trevethin Community School which closed in 2007.
The school has been known by a variety of names over the last 100 years. Originally conceived as Jones' West Monmouth School it has also been known as Haberdashers' West Monmouth School, West Monmouth Boys' School and in later years West Monmouth Grammar School. Today the school is often referred to as West Monmouth Comprehensive School. Internally the school use the shorthand names West Mon or WMS. There is at least one plaque in the school that refers to it as Jones' West Monmouthshire School. The official name, however, is West Monmouth School.
