Opened in 2007, this architecture and heritage museum impresses principally by its scale. The expansive ground floor is filled with life-size mock-ups of cathedral façades and heritage buildings, and interactive screens place the models in context. Upstairs, darkened rooms house full-scale copies of medieval and Renaissance murals and stained-glass windows. The highlight of the modern architecture section is the walk-in replica of an apartment from Le Corbusier's Cité Radieuse in Marseille
It makes for a fascinating visit for children of all ages; to help them understand the exhibits, colourful interactive games are dotted around the permanent displays, so they can try their hand at architecture and learn the concepts of Romanesque and Gothic as they create fantastical animal heads, design stained-glass windows or build a Romanesque arch.
On Saturdays at 2pm, three- to seven-year-olds can have a go at doing some building themselves with wooden blocks. Entry is €8 and you don't need to reserve (just turn up about 30 minutes beforehand).
