The Burggarten is a once-royal garden that is a bit of England in Vienna, as it is patterned after English gardens.
The Burggarten was the court garden for the Hapsburg rulers. One Austrian ruler, Kaiser Franz II used to work in the garden, which is now a place where people can enjoy outdoor lunches on pleasant days.
A memorial to that great Austrian composer, Mozart, can be found in one corner of the garden, while the Palmenhaus, a magnificent glass palm house, is located in the northern part. The left part of the Palmenhaus houses the Schmettlerlinghaus where visitors can see tropical butterflies and even bats.
