Colwyn Bay (Welsh:Bae Colwyn) is a town, community and seaside resort in Conwy County Borough on the north coast of Wales overlooking the Irish Sea. Eight neighbouring communities are incorporated within its postal district. Established as its own separate parish in 1844 with just a small grouping of homes and farms where the community of Old Colwyn stands today, Colwyn Bay has expanded to become the second-largest community and business centre in the north of Wales as well as the 16th largest in the whole of Wales with the urban statistical area having a population of 28,992 at the 2001 census. Locally nicknamed "The Bay".
