Cork's history began in the 7th century with the founding of a monastery by St. Finbarr on a small alluvial island in the River Lee. The monastery and the settlement were later incorporated in the fortified base the Danes developed there. As a result of war and destruction throughout the following centuries, Cork has no medieval buildings left but boasts a few remains from the 18th century. The central area takes its architectural character from the early 19th century.
