Wheal Grenville
Wheal Grenville began to be worked in the 1820s though it was not productive until the 1850s, at which time the South and East mines were worked independently. In 1906 these mines were united with South Condurrow to form the Grenville United Mines and continued in operation until 1920. There was an abortive attempt to reopen the mine in the 1960s. The engine houses were consolidated in the mid-1990s as part of the Mineral Tramways Project. The mine now forms part of the the Conrish Mining World Heritage Site.
