Belgium has cities which are modern and cities which are old. Myself I like the old ones the most. I visited Leuven, Brussels, Antwerpen and Bruges. Except for Brussels the cities are not very big but beautiful. Myself I liked Bruges the most. But even the other cities I visied are worth visiting. Besides walking around and watching beautiful buildings Belgium is good if you like churches. There are very many beautiful churches in Belgium and you can never finish watching all of them.
