Hoosesaggmuseum, Miniature museum in Basel, Switzerland

The Hoosesaggmuseum is a single glass display case set into the front door of the house Zum großen Christoffel at Imbergässlein in Basel's old town. The case shows one collection at a time, changed monthly, with eight collections a year; past displays have included pill boxes, sunglasses, toy airplanes, cowbells and red London bus models. Each exhibited item fits inside a trouser pocket.

The museum was established in 1995 within a medieval house dating to 1345 that survived the 1356 Basel earthquake. The building retains its historical character and displays Saint Christopher imagery from its past.

The name Hoosesagg is Basel German for trouser pocket, and every exhibited item must fit inside one. Eight collections rotate each year, one per month, following the seasons: pill boxes, sunglasses, toy airplanes and cowbells have been shown, and red London bus models were displayed for the 2012 London Olympics. Anyone with a collection of at least 30 pieces can exhibit; the Vergeat family arranges the window themselves.

This free exhibition is located in central Basel and can be viewed from the street at the entrance door of a residential building. Since items are displayed in a compact glass case, the entire collection can be observed quickly during a brief stop.

The name comes from a Basel dialect word meaning trouser pocket, and every item on display must actually fit inside one. This pocket-sized constraint becomes a creative challenge that shapes what collectors choose to exhibit.
