Flak towers (Flaktürme) were eight complexes of large, above-ground, anti-aircraft gun blockhouse towers constructed by Nazi Germany in the cities of Berlin, Hamburg, and Vienna from 1940 onwards. The towers were used by the Luftwaffe to defend against Allied air raids against these cities during World War II. They also served as air-raid shelters for tens of thousands of local civilians.
In Vienna military authorities chose the Augarten as one of several places to erect massive buildings for anti-aircraft defence to protect the inner city from Allied bombing. During summer 1944 the construction of a 55 metre high tower with platforms for anti-aircraft guns and nearby also a 51 metre high control tower was begun but not finished. Their remains are still visible in the middle of the park. Moreover during the war hundreds of cubic metres of rubbish were dumped on the site whilst armoured vehicles criss-crossed the garden and - as it is supposed - common graves were dug for hundreds of war victims.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.
