OK 3 euros to get in but the staff outnumbered the visitors when I was there! Instead of one handout describing the artifacts, each room had separate ones which was confusing at first and frustrating. That said some of the silverware was awesome including a large chest which really took my eye. As it's under-lit to save damage and you can't use a flash the only way to keep a record is with video and whilst my camera has the facility the quality isn't brilliant so a good low lux camcorder is best. The Flemish artists never could paint "young faces", cherubs and the like in the same way the Italian masters did so the paintings were a little unrealistic in some cases with children/cherubs depicted. It's worth a visit to see everything plus the wooden carvings, some have aged better than others ( dreaded worm has struck some!) but when you consider how old they are some have remained remarkably intact.
