Rubislaw quarry
From Wikipedia, the free encyclopedia
Rubislaw Quarry was opened in 1740 and is located at the Hill of Rubislaw in the west end of the Scottish city of Aberdeen. In 1778, Aberdeen city council sold it to a businessman, as it was not though to be a source of good building material. However, over the next 200 years, an estimated six million tonnes of granite were excavated from the quarry, giving Aberdeen the name of 'The Granite City'. Rubislaw Quarry is the biggest man-made hole in Europe.
John Smith and Archibald Simpson were architects who constructed some of Aberdeen's best known buildings from granite in the early 19th century. Waterloo Bridge in London, the terrace of the Houses of Parliament and the Forth Rail Bridge were also constructed with granite from Aberdeen. Matthew Forster Heddle found the quarry a good source for the minerals tourmaline and beryl.
Today, the fine gray granite from the quarry is visible in the majority of Aberdeen's buildings, but Rubislaw quarry has been closed since 1971. Although the quarry is 142 m deep and has a diameter of 120 m it has been neglected and is now filled with water. It has never been marketed as a tourist attraction. The quarry is inaccessible, hidden by trees and surrounded by flats and office buildings.
