Museum aan het Vrijthof occupies one of the oldest buildings on Maastricht's central square, a former retreat associated with Charles V. It is a small private museum with a changing programme of art, design, photography, and cultural history exhibitions.
The draw is as much the setting as the collection: the museum gives you a reason to step inside one of the Vrijthof's historic houses instead of only seeing the square from the outside. Check the current exhibition before going, as the experience depends heavily on what is on show.
