AtomiumThe big round things you see in every Brussels guide is the Atomium building, which was built for the first post war universal world exhibition. A 5 minute walk from the Heysel/ Heizel metro station and you reach the Atomium. I suggest taking your time and walking around the area, looking at that unusual architecture. A fee of 11 euro has to be paid to visit the building where you can find exhibitions explaining how and why the Atomium was made, an observation deck giving you a view of Brussels.
Manneken PisVisiting Manneken Pis is as compulsory as eating a Belgian waffle. The most famous boy in Brussels, Manneken Pis is a bronze statue of a boy peeing. He is dressed in a different attire every day. The interesting thing here is that, the concept of this varies from person to person. I don’t think anyone knows the “real” story, if you do, then please share it with me.
