The place is well known for its castle, Schloss Laxenburg, which, beside Schönbrunn, was the most important summer seat of the Habsburg dynasty.
This castle became a Habsburg possession in 1333 and was extended in the 17th century by Lodovico Burnacini. The Blauer Hof (German for: blue court) or Neues Schloss (German for: new castle) was built around 1745 during the reign of empress Maria Theresia and has a Rococo interior.
The church of Laxenburg, which was the first building north of the Alps containing swung facade components (characteristics of the high baroque), was built between 1693 and 1703 by Carlo Antonio Carlone and continued between 1703 and 1724 by Matthias Steinl.
After 1780, the castle garden was rearranged as an English landscape garden. It contains several artificial ponds, and, on an island, the Franzensburg castle, named after emperor Franz I, can be found.
