Schönbrunn Palace

It began as a hunting lodge that Leopold I had turned into a palace in the late 17th century, and Maria Theresa made it the court's grand summer residence, with 1,441 rooms. In the Hall of Mirrors, six-year-old Mozart played for the empress. Franz Joseph was born and died here. It has been a UNESCO World Heritage Site since 1996.

The Baroque gardens run down from the façade to the Neptune Fountain and up the hill to the Gloriette, a colonnade from 1775 looking over the palace and Vienna. The park also holds fake Roman ruins, a maze and the world's oldest zoo still operating, founded in 1752.
