The 18th century antiquary, Iolo Morganwg, inventor of the present-day rituals of the National Eisteddfod of Wales kept a bookshop in the High Street, the location of which is now marked with a plaque inscribed in Welsh and ogham script. It was just outside the town that he held the first meeting of the Gorsedd, an assembly of bards, in 1795. Cowbridge Grammar School was founded during the 17th century and had close links with Jesus College, Oxford through its founder, Dr Leoline Jenkins. Its famous pupils included the poet, Alun Lewis, and the actor, Sir Anthony Hopkins. It was eventually turned into a comprehensive school, and the buildings, having for some time lain derelict, are about to undergo refurbishment for an alternative use.
