The name is the story. Gruut was a mixture of dried flowers and herbs used to flavour and preserve beer before hops took over, and the Van Gruuthuse family held the right to levy the tax on it in Bruges. Beer money built this. The house is a genuine 15th-century city palace, not a museum built to look like one, and it stands directly against the Church of Our Lady.
Louis de Gruuthuse (Lodewijk van Gruuthuse, c. 1427–1492) is the man the building is really about, and he is squarely our audience’s kind of figure: soldier and diplomat for the dukes of Burgundy, knight of the Order of the Golden Fleece, and the owner of one of the finest illuminated libraries in Europe. His statue stands in the museum under his personal motto, Plus est en vous — “there is more in you” — which is carved and painted throughout the house.
The single best thing here costs nothing extra and is easy to walk past. The oratory, an authentic late-15th-century private prayer box, is built through the wall into the chancel of the Church of Our Lady, so that the family could hear mass from inside their own home. You stand in it and look down into a Gothic chancel from a window that a duke’s chamberlain had cut for himself. There is also a balcony with a view over the Dijver and the Bonifacius bridge.
The route runs through three periods: Bruges in its Burgundian prime, then the neglected 17th and 18th centuries, and finally the 19th-century “rediscovery” of Bruges and its rebuilding in neo-Gothic. That last part is why this museum matters more than its ticket price suggests. Almost every other site in town shows you the result of that rebuilding without naming it; this one takes it apart, with the tapestries, stained glass, carved wood, lace and porcelain to show what was collected, copied and invented. Do the Gruuthuse before you walk round the Burg and the Markt, and you will read both squares completely differently.
The museum closed in 2014 and reopened on 25 May 2019. Entry is now through a new glass-and-steel pavilion set between the palace and the church — modern, deliberately so, and the source of most of the complaints about the place.
