POINTS OF INTEREST
Built in the 1780s in the classical style, this opulent, green palais hosted the world premiere of Mozart's opera Don Giovanni in October 1787 with the composer himself conducting. Prague audiences were quick to acknowledge Mozart's genius: the opera was an instant hit here, though it flopped nearly everywhere else in Europe. Mozart wrote some of the opera's second act in Prague at the Villa Bert, where he was a frequent guest. The program these days is mostly demanding Czech drama, though you can occasionally catch a more accessible opera or musical performance. You must attend a performance to see inside; buy tickets at the Narodní Divadlo.
