Heritage Open Day: Visit this simple, peaceful church to rest a while or to see the stunning window by the world-famous Irish stained glass artist Harry Clarke or works by renowned local sculptor Fenwick Lawson. Completed in 1827 by local architect Ignatius Bonomi, St Cuthbert's Catholic Church is in a part of Durham that was often called 'Popish Elvet' because of the number of Catholic residents. The church is a hidden gem opposite one of Bonomi's other major works - Durham's Crown Courts! Although the church is simple in its architecture, it contains a spectacular stained glass window by the Irish artist Harry Clarke.
