English Cathedrals - Bangor Cathedral - One storey building , pillared frontage railings , people in (foreground). Part of Box 144 Boswell Collection - English Cathedrals .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.
