Rebuilt in a Baroque architecture, Baroque style by the master builder Lodovico Burnacini, it became the centre of extended gardens and pleasure grounds. From 1710 onwards the Baroque ''Blauer Hof'' (Blue Court), also named ''Neues Schloss'' (New Castle), was built according to plans designed by Johann Lucas von Hildebrandt as the residence of the Habsburg vice-chancellor Friedrich Karl von Schönborn. Later Empress Maria Theresa acquired the palace and from 1756 onwards had it lavishly rebuilt by her court architect Nicolò Pacassi with a Rococo interior. Laxenburg became the favourite residence of Maria Theresa and her descendants. The parish church of Laxenburg was erected vis-à-vis between 1693 and 1703 by Carlo Antonio Carlone.
