About the location (from Wiki):
Wenceslas Square is one of the main city squares and the centre of the business and cultural communities in the New Town of Prague, Czech Republic. Many historical events occurred there, and it is a traditional setting for demonstrations, celebrations, and other public gatherings. The square is named after Saint Wenceslas, the patron saint of Bohemia. It is part of the historic centre of Prague, a World Heritage Site. Less a square than a boulevard, Wenceslas Square has the shape of a very long (750 m, total area 45,000 m²) rectangle, in a northwest–southeast direction. The street slopes upward to the southeast side. At that end, the street is dominated by the grand neoclassical Czech National Museum. The northwest end runs up against the border between the New Town and the Old Town.
