Bangor Cathedral is a place of Christian worship situated in Bangor in North Wales in the United Kingdom. It is dedicated to Saint Deiniol. The present building of Bangor Cathedral is not particularly old, but the site has been in use since the 6th century. The cathedral is built on a low-lying and inconspicuous site, possibly so as not to attract the attention of raiders from the sea. Visitors to Bangor often assume that the Gothic style building on the hill is the cathedral, but this is actually part of the University.
