ne circles St Austell town centre showing the railway station and residential houses; in the distance, on the horizon, are huge pyramidal china clay spoil heaps. St Austell was formerly an 18th century tin mining hub before the discovery of china clay in the area.The china clay industry came into its own during the mid-19th to early 20th centuries, at a time when the falling prices of tin and other metals forced many mines to close down or convert to clay mining.
