Medieval reenactment event at Gaasbeek Castle with a tent camp and knights.

On September 26 and 27, hundreds of reenactors from 12 countries will gather at the Castle of Gaasbeek and the adjacent Groenenberg domain for a large-scale medieval revival.

For two days, hundreds of reenactors will descend upon the grounds of the Castle of Gaasbeek and the adjacent Groenenberg domain. They will participate in jousting, archery, and sword fighting tournaments, and daily join in “the siege of Gaasbeek”. Participants will sleep, eat, and live in an extensive tent camp with inns and food markets, complemented by over 40 medieval merchants and dozens of animations and extras.
Beyond a visual total experience, Quondam aims to be interactive. Both young and old can actively participate in the craft village and the squire school.
