The Rhondda Valley in South Wales was the centre of coal mining from the 1850s to the 1980s. These tiny grey houses were owned by the mine owners until the mining of coal was profitable. As soon as it lost from its great profits they sold them to the poor mining families. Since the 1980s when Thatcher's government implemented the closure of the mines unemployment, drug abuse, teenage pregnancy and alcoholism is one of the highest here in the entire UK.
