Kind of Paris Champs-Élysées :). Just kind of, of course. BUT Prague Wenceslas Square is really a boulevard/avenue, measuring 750m long by 60m wide.
The history of the square goes back to 1348, when Charles IV (Czech king and Holy Roman Emperor) designed it as a horse market. After 600 years it is now a national symbol and the place where most demonstrations take place.
It’s a perfect place for going shopping, meeting friends or just hanging out. It is in fact one of Praguers’ favorite meeting places (“at the Horse’s tail”) and a great spot to start your itinerary around the city.
At the top of Wenceslas Square, there is the monumental National Museum, and just off to the left is the Prague State Opera.
Wenceslas Square is not only the home of Czech history and the cultural centre of Prague, but it is also one of the most popular shopping venues of the Czech Republic’s capital. In addition to numerous occasional and regular markets, such as Easter markets or Christmas fairs, taking place at the square, there are also a great number of shops there. One can buy pretty much anything, from souvenirs to groceries, at Wenceslas Square.
The shops are placed along both sides of the boulevard, and when you are tired you can rest either in one of the many cafés or restaurants, or just sit on a bench in the centre of the square. A significant part of Wenceslas square is nowadays a pedestrian precinct, which contributes to the fact that so many people like to spend their leisure time there, shopping, meeting friends, or just strolling…
