Our favorite unusual museums in Brussels
The Crossbow Museum

The Crossbow Museum is a living museum where you can learn more about the history of the mysterious crossbow weapon and the prestigious Crossbow Guild. But you can also watch real shooting demonstrations by the Companions of the Great Oath.
But who are these Companions of the Great Oath? In fact, they are a corps of crossbowmen heir to the Gildes d’Arbalétriers, whose creation dates back to the 12th century. Their predecessors were charged with protecting the city of Brussels. This museum was born of a passion for the crossbow and its history. It contains a collection of over 1,500 pieces and receives between three and five thousand visitors every year. And on Thursdays, visitors can try their hand at crossbow shooting with the Compagnons!
