Autoseum, Transportation museum in Simrishamn, Sweden.

The Autoseum is a transportation museum in Simrishamn displaying cars and motorcycles from multiple periods and manufacturers. The collection spans over 200 vehicles arranged across approximately 2,500 square meters of exhibition space.

The collection began with Skoklosters Motormuseum, founded in 1963 by Rutger von Essen, the last private owner of Skokloster Castle. After his death in 1977 Gunnar Wretner bought it, and his son Thomas Wretner sold it in 2007 to Uno Levinsson, Torbjörn Wistrand and Håkan Mårtensson. In June 2008 it opened in Simrishamn as Autoseum, keeping the whole collection except the engines, which were sold separately.

The separate Frasses & Mariannes Musikmuseum holds what the source calls the world's foremost collection of Edison phonographs. Its founder, Frasse, began studying Thomas Alva Edison and collecting his phonographs after first reading about him in 1964. The objects are kept in the Stiftelsen Frasses och Mariannes Musikmuseum foundation.

The museum occupies a single-storey building with ribbed light grey metal panels; the entrance is at the right end, through two large grey double doors with small square windows. Signs on the facade read "AUTOSEUM" and "Nisse Nilsson Collection". The outdoor area holds a Saab 35 Draken airframe, visible without entering the exhibition halls.

The museum also holds SMOS, the Swedish Vintage Model Flyers' Society collection, described in the sources as the only museum of its kind in Sweden. It sits alongside the car halls, the Stefan "Lill-Lövis" Johansson racing display and the Frasses & Marianne music collection under one roof.
