4Schonbrunn Gardens, Vienna, Austria

The Schonbrunn gardens are just one of the many reasons why Viena (together with another famous city) is the most beautiful European capital city.

The Schonbrunn Palace was the main summer residence of the Habsburg rulers, the family that once ruled the Austro-Hungarian empire, Europe’s second-largest state (just after Russia). The gardens, which feature long, tree-lined passageways, are among the most beautiful in Europe. A large palm house was built in the gardens in 1882, creating a tropical environment for visitors.
