The ruined castle Burg Drachenfels, on the summit of the Dhill, was built between 1138 and 1167 by Archbishop Arnold I of Cologne and bears the same name. It was originally intended for the protection of the Cologne region from any assault from the south. Originally it consisted of a bergfried with court, chapel and living quarters for servants. The castle was slighted in 1634, during the Thirty Years' War, by the Protestant Swedes and never rebuilt. As a strategic asset it had outlived its usefulness. Erosion due to the continued quarrying undermined much of the remains and only a small part is left today.References:
Claude Monet lived for forty-three years, from 1883 to 1926, in Giverny. With a passion for gardening as well as for colours, he conceived both his flower garden and water garden as true works of art. Walking through his house and gardens, visitors can still feel the atmosphere which reigned at the home of the Master of Impressionnism and marvel at the floral compositions and nymphéas, his greatest sources of inspiration.
In 1890 Monet had enough money to buy the house and land outright and set out to create the magnificent gardens he wanted to paint. Some of his most famous paintings were of his garden in Giverny, famous for its rectangular Clos normand, with archways of climbing plants entwined around colored shrubs, and the water garden, formed by a tributary to the Epte, with the Japanese bridge, the pond with the water lilies, the wisterias and the azaleas.
Today the Monet's Garden is open to the public.
