Pontefract, Italy
The Prince of Wales Colliery was a coal mine that operated for over 130 years in Pontefract, West Yorkshire, England. It was permanently closed in 2002 after geological problems were found to make accessing remaining coal reserves unprofitable, and most of the site was later converted for housing.
