Vienna’s Stadtpalais Liechtenstein, the city palace that launched a revival of Rococo in the mid 19th century, will offer public tours for the first time on Friday after an extensive face-lift.

The late 17th century palace was once the main residence of the princely family of Liechtenstein, one of Vienna’s richest families considered to be at the cutting edge of art and architecture, before they moved to the tiny Alpine principality.

The Baroque building, which was revamped in the 1840s in the neo-Rococo style, was damaged during a bombing raid in World War II and when an Allied aircraft crashed into its roof in the final days of the war but it remained standing.
