Cowbridge Grammar School was one of the best-known schools in Wales until its closure in 1974. It was replaced by Cowbridge Comprehensive School.
Founded in the 17th century by Sir John Stradling and refounded by Sir Leoline Jenkins, it had close links with Jesus College, Oxford. The school took both boarders and day boys. Famous old boys include actor Anthony Hopkins, poet Alun Lewis, and TV presenter Patrick Hannan.
The main school buildings were located in Church Street, Cowbridge. Derelict for some years, they have now been converted into residential accommodation. The school also occupied part of Old Hall, now an adult education centre.
Unfortunatly the school is to be demolished in 2024 to make way for housing.
