An Tur Gloine

An Tur Gloine was a cooperative studio for stained glass and opus sectile artists, based in Dublin, Ireland, from 1903 until 1944. It was founded in January 1903 by Sarah Purser, who ran the studio until 1940, when Catherine O'Brien took over until its closure in 1944. Purser established it with the support of cultural activist Edward Martyn to give Irish churches and architectural commissions an Irish-made alternative to stained glass imported from England and Germany.
