Burggarten Vienna or Castle Garden is a leafy oasis with a breathtaking ambiance. Burggarten has a very interesting history. Vienna was surrounded by an ineffectual defensive wall when Napoleon invaded. He destroyed large portions of the wall when he left in 1809, leaving a wide-open space where the garden would be created. It was originally designed as a private garden for the emperor but opened to the public in 1819.
Some attractions in the area are the monuments and statues of famous public ﬁgures, such as one of Hercules ﬁghting a lion, a Franz Josef statue in full military garb and the famous Mozart monument.
Just North of Burggarten, the Palmenhaus is a magniﬁcent glass palm house designed by Friedrich Ohmann. The structure was built between 1901 and 1907 as a greenhouse. There is a popular café in the center of the house, and on the left there is the butterﬂy house, where you can watch tons of free flying tropical butterflies.
