Maison de la boîte à mouches, Medieval house in Colmar, France

The Maison de la boîte à mouches is a narrow half-timbered house at 11 place de l'École in Colmar, with dark wooden beams crossing ochre-brown and cream panels. Its lower section has a white-framed louvered shutter and a smaller window with a bracket lamp; a red-brown tiled roof covers the upper part, where a dormer with a small white-framed window sits in a gabled projection. A grey downpipe runs along the right side of the facade.

The building was reconstructed in 1948 following World War II damage while maintaining its original medieval character. During the Middle Ages this location served as part of the monitored entry point for merchants approaching the old town.

Locals call it Muckekaschtele, Alsatian for "little fly box", a name tied to the small fly traps once kept in regional households. The facade's dark beams over ochre-brown and cream panels, with a louvered white shutter and a bracketed lamp, show the half-timbering rebuilt in 1948 after wartime destruction.

The house stands at 11 place de l'École, in the old town of Colmar, not near Place Rapp. Its facade faces the square, so it is seen on foot while walking through the pedestrian centre; the timber framing, the ochre and cream panels and the grey downpipe along the right side help identify it.

The name refers to small containers once used to trap houseflies in everyday households across the region. These practical devices were so common that they gave the house its lasting name.
