Erich Kästner Museum, Literary museum in the Innere Neustadt, Dresden, Germany

The Erich Kästner Museum is a mobile micromuseum installed on the ground floor of the Villa Augustin at Antonstraße 1 in Dresden's Innere Neustadt. Its wooden block, 3 by 2 by 1.2 metres when closed, holds a multimedia core with original exhibits and 13 movable modules with colour-coded drawers. The unit stands on small wheels and can be walked around.

The museum was founded in 1999 and opened in early 2000, the 101st anniversary of Kästner's birth, in the Villa Augustin at Albertplatz in the Innere Neustadt. The villa had belonged to his maternal uncle Franz Augustin, a horse trader, and the young Kästner visited it often; he later recalled the house and its surroundings in When I Was a Little Boy. The museum was funded entirely by private donations organised by the Förderverein für das Erich Kästner Museum.

The museum's name comes from the author, but the villa's name recalls his uncle Franz Augustin, a horse trader. Kästner's cousin Dora Augustin, nicknamed "Pünktchen" (little dots), and the adjacent Antonstraße gave their names to the main characters of Pünktchen und Anton. A bronze sculpture by Mathyas Varga shows the boy Kästner perched on a wall, listening to the trams on Albertplatz.

The museum occupies a single 30-square-metre room on the ground floor of the Villa Augustin at Antonstraße 1, by Albertplatz in the Innere Neustadt. The tram stop is announced as "Albertplatz - Erich Kästner Museum". The wooden micromuseum stands on wheels, so the room can be crossed on foot in a few minutes; the drawers are meant to be opened and handled.

The museum's 1998 design by Irish architect Ruairí O'Brien was conceived as a "walkable treasure-chest" of mobility, interaction and compactness. The travelling twin exhibition, opened in 2014, has since visited Washington D.C., Omsk, London and Tokyo. The museum won the Heinz and Brigitte Schirnig Foundation's Museum Prize in 2002.
