Stay out late this Saturday night to explore some new sides of old Prague. Now in its ninth year, the city’s Museum Night offers an after-hours glance at the city’s museums, galleries and other cultural landmarks. This year, 39 institutions offer special programs in about 70 buildings. Entry and use of public transportation are free from 7 p.m. Saturday to 1 a.m. Sunday.

Your night could include listening to a chamber orchestra playing Beatles songs, trailing a wounded dinosaur through a fossilized forest, an ascent of the tower of the New Town Hall, or making candy violets.
