A 1 mile circular walk around Llanymynech Heritage Area. The route: Two hundred years ago Britain was the most powerful country in the world. Places like Llanymynech became hugely important because of what they produced here. Donkeys and horses were vital to pull the carts full of stone. They looked after them here. These kilns look like massive castle walls but they are not. They are huge ovens used to turn Limestone into quicklime. The Hoffman Kiln is the biggest oven of all. It burned day and night. The dust in the air mixed with moisture and sweat, burning the kiln workers skin and lungs.
