The Hoosesaggmuseum, or "Trouser-pocket museum" in English, is tucked away in a twisting alley off Nadelberg. The box, which is fitted into a house door, is the smallest lost place in Basel, measuring less than half a square metre. The idea of the Hoosesaggmuseum came about through necessity. A small window in the door provided a glimpse into the house, which is more than 600 years old. Troubled by the curiosity of passers-by, the family fitted a wooden box behind the window and started to display small items in it. The objects are now changed in line with the seasons, and make reference to various current world events.
