I really love this set of buildings in Oude Markt, just off Grotte Markt.
I passed by them so many times and never had a moment to spare to take a photo and to really look at them.
Others seems to be doing the same thing. During the holidays every single tree in the square is decorated with sparkly lights.
Leuven is a little town but so beautiful. It is a must in my opinion when visiting Belgium.
