The 750m long and 60m wide boulevard that makes up Wenceslas Square was laid out over 600 years ago during the reign of Charles IV.
It was originally used as the main Prague horse market.
Over the years it has been a regular parade ground for all kinds of organisations and political parties.
From anti-communist uprisings to celebrating winning the World Ice Hockey Championships, this is where Czech's come to let off steam.
Wenceslas Square comfortably holds up to 400,000 people!
