St Columb’s Cathedral was built between 1628 and 1633 at the highest point in Derry City on the site of a former Cistercian Nunnery. It is Derry’s oldest surviving building and is also the first Protestant Cathedral to be built in the British Isles after The Reformation. It was built for the ‘new settlers’ who arrived from England and Scotland during the plantation of Ulster and paid by the Corporation of London. It was designed to resemble a medieval English parish church and is dedicated to St Columba who established the first Christian settlement near this location in the 6th century a.d. It has lots of interesting memorabilia, furnishings and stain glass windows some of which date back to 1600.
