Garthewin is the name of one of the most gracious of Welsh houses, but by this it has come to mean even more for the life of Wales. For here, serenely set in the hills and looking down to the vale of Elwy, a Georgian mansion, with all its privilege of place, has become a centre for the Welsh theatre. In 1937, Mr Robert Wynne, the owner of Garthewin, decided to convert a bam on his estate into a little theatre. The barn itself was built about 1770 of undressed stone, but within it had two remarkable features—a pair of brick arches—which lent themselves to the perfect adaptation of a simple building into a place where plays could be worthily, and audibly, performed. One arch forms the proscenium, and the theatre itself can accommodate about two hundred people. At Christmas it is the setting for the celebration of Midnight Mass.

To begin with, Garthewin was used for occasional performances by amateur companies. It is not easily reached, and its immediate audience is drawn from the villages and scattered farms nearby. But at once its autonomy as a theatre, free from the irrelevant associations of chapel vestries and village halls where plays are generally only a means of raising funds for some local cause, gave a new seriousness to Welsh drama. Experimental plays and translations of European classics found a home at Garthewin, and the theatre, lying in the very shadow of the mansion, seemed to symbolize the emergence of the Welsh drama as the new inheritor of that unbroken cultural tradition which is the glory of Wales.
