After every two years an event called "The Brussels' Flower Carpet" is celebrated, where a huge flower carpet is laid down at front of main city Hall on main square in Brussels. Watching carpet is free but if you want to have a clousure view you have to pay 3 Euros for a better preview from buildings. Around 700,000 flower had been use to make carpet this year. The festival started at August 13 & will open till 15th of August.
