Monkwearmouth Colliery
From Wikipedia, the free encyclopedia
Monkwearmouth Colliery (or Wearmouth Colliery) was a major North Sea coal mine located on the north bank of the River Wear in Sunderland. It was the largest mine in Sunderland and one of the most important in County Durham. It first opened in 1835. The mine was the last to remain in the County Durham Coalfield and was finally closed in June 1994, ending over 800 years of commercial coal mining in the region.[1] The Colliery site was cleared a few years later, and the Stadium of Light was built over it.
