It is a long, low, flat land of grass and water. Greys and blues and sof greens are the colours. But sometimes, when the sun goes down, the sky and land are a wonderful red and gold. In the spring of 1930 a man bought some land and an old, empty lighthouse standing at the mouth of the little river Aelder. The man's name was Philip Rhayader. He lived and worked alone at the lighthouse all through the year. He was a painter, and he painted pictures of the birds and the marsh.
