Britain’s smallest city, St David’s, is dominated by its cathedral. St David, the patron saint of Wales, founded a monastery on the site where the cathedral now stands in AD 589 and it became a major place of pilgrimage. The cathedral dates from 1181 and contains many things of historical interest. In the south transept there are some fine Celtic carvings on the Abraham Stone, the gravestone of the sons of Bishop Abraham who was killed by Vikings in 1080. Every May and June, the cathedral hosts the St David’s Cathedral Festival, featuring nine days of classical music performances.
