Bangor Cathedral is an ancient place of Christian worship situated in Bangor, Gwynedd, north-west Wales. It is dedicated to its founder, Saint Deiniol. The site of the present building of Bangor Cathedral has been in use as a place of Christian worship since the 6th century. The cathedral is built on a low-lying and inconspicuous site, possibly so as not to attract the attention of Viking raiders from the sea. Some visitors to Bangor assume that the Gothic style building on the hill is the cathedral, but this is actually part of the university.
