Daugavgrīva Castle was originally a monastery converted as a fortress by Swedish in the 17th century. Today there are no remnants of the medieval castle above the soil.
In 1208 there was a Dünaburg castle built by the Teutonic Knights which initially served as a monastery. The Swedish fortress of Dünamünde, designed in a Dutch style by General Rothenburg in 1641, replaced the ruined Daugavgrīva Castle by 1680. In 1695 the Commandant was captain Heinrich Nicolaus Rüdinger, forefather of future Patriarch Alexy II of Russia. Rüdinger was knighted by Charles XI of Sweden. Joachim Cronman later became the Commandant and he died on March 5, 1703.
After the fortress was seized by the Russians they reconstructed it. Regent Anna Leopoldovna of Russia, her husband Anthony Ulrich, and her son Ivan VI were incarcerated in Dünamünde in 1742. A local Lutheran church was rebuilt into the Orthodox Church of the Saviour's Transfiguration in 1775. The Russian government renamed the fortress, where only Russian soldiers were living, to Ust-Dvinsk in 1893. They had its fortifications completely reconstructed prior to World War I. During the war Ust-Dvinsk was bombarded by the Schütte-Lanz Airship SL 7 of the German Army. After the fortress was taken by Imperial Germany, it was inspected by Emperor Wilhelm II in 1917. The Latvian government, however, demolished much of the fortifications several years later. During the Cold War Ust-Dvinsk was a base for Soviet troops. The site is now known in Latvian as Daugavgrīva. There is a functional lighthouse at Daugavgrīva which was originally built in 1818. It was rebuilt in 1863, 1920, and after World War II.
Nowadays entrance in the area of castle goes along the northeastern corner. Still there is partly visible the old road which was leading from northeastern tower around the forepart of the castle up to the southeastern corner.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.
