Don't waste your money going on the tour if you can't speak French or Flemish, I was given a brochure in English and told very sternly I had to go on the guided tour. Waited around for half an hour then the tour started with this guy repeating the information in the two languages. It was so dark inside I couldn't read the brochure so I had no clue what it was about, people were getting bored and children were starting to cry. After the third stop In front of some very and old dusty dummies and cardboard cut outs very amateurish, I left. The views are fine but even if you want to walk up the steps they still charge you. As well as charging entrance fee they charge for the use of the toilet facilities, which is a woman chain smoking outside your door!
