Booked our trip last year and rented a great Air BnB flat in Brussels so we could see the amazing flower carpet that is created in Grand Place. The event was in August, but I'm so far behind getting posts up! They don't do this every year, so we were glad we knew about it and were able to go this year. It was Japanese themed this year. The flowers are placed on Thursday night and are displayed through Monday, with it completely disappearing by Tuesday morning.
Such an incredible sight!
