Brinksway Caves

The Brinksway Caves, also known as Maggie's Caves, are a group of artificial caves on Brinksway, beside the River Mersey in Stockport, Greater Manchester, England. They were excavated by workers cutting into naturally eroding sandstone on the Cheadle side of the river. Dating back to at least the 17th century, they have been expanded and used for various purposes, including industrial activity in the 19th century and as air-raid shelters during the Second World War. In the present day they are occasionally used as informal shelter, and their position above the river has led to several accidents.
