Llanfairfach

Llanfairfach was a small town located in Wales. It was home to both a coal mine, the main source of its economy, and a commune named Wholeweal.

In the 1970s, the Coal Board closed the coal mine, causing the loss of many jobs. However, Global Chemicals later opened a oil refinery there, promising prosperity for the town, although Clifford Jones opposed it over environmental concerns. The Third Doctor and Jo Grant went to Llanfairfach to investigate the mysterious death of Hughes, whose body had been found glowing green. They discovered that Global Chemicals was dumping lethal toxic waste into the abandoned mine, which also had the side-effect of creating Giant Maggots, and the refinery was shut down.

Luckily, thanks to string-pulling by Jo Grant, the United Nations decided to fund the Wholeweal commune as a research facility: the money and extra work needed brought jobs to the town. (DW: The Green Death)
