Ragnhildsholmen was a medieval castle built by Håkon Håkonsson (Haakon IV) of Norway around the year 1250. The castle was first time mentioned in 1275. In 1304 it was donated to duke Erik in 1304 and saw the power struggle between Swedish Kings Birger and Magnus III. After the near Bohus Fortress completed, Ragnhildsholmen lost its purpose. It was demolished and stones were probably used to build Bohus. Today impressive ruins still stands on the site.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.
