Gustav III's Collection including his own and other famous architects' drawings, accompanied Gustav IV Adolf during his exile in 1809. The collection was returned to Sweden via a purchase in 1925 by the brothers Helge and Axel Ax:son Johnson and was inherited by Axel's daughter Marie- Claire. It is today stored at Engelsberg's Ironworks and is owned by the Marie-Claire Cronstedt Foundation. The drawings were made by Sweden's leading architects during the 17thand 18th centuries and include, among others, the castles and gardens at Drottningholm, Ekolsund, Haga, Gripsholm, Karlberg, Ulriksdal, Svartsjö, Stockholm and Uppsala. Even Gustav III's own sketches are attributed.

Sommaren 1777 slog en nyhetsbomb ned i Europa. Katarina den stora fick oväntat besök - av en greve av Gotland som i själva verket var Gustav III av Sverige. Han hade i det längsta hållit sina planer hemliga för att inte väcka onda aningar vare sig hos vänner eller fiender. Detta är berättelsen om Gustav III:s ryska resa, fylld av anekdoter och dramatiska ögonblick. Magnus Olausson bygger sin skildring delvis på en ganska okänd resedagbok som fördes av kungens närmaste man. Det blev en händelserik månad i S:t Petersburg. Magnus Olausson är fil dr och 1:e intendent vid Nationalmuseum med särskilt ansvar för Statens porträttsamling vid Gripsholms slott.

The Nationalmuseum in Stockholm is home to the world's largest collection of miniature paintings, 5,700 in all. The majority of them are are portrait miniatures, by Swedish and other European artists from the 16th century down to the middle of the 20th. The collection is remarkable not only for its size, but just as much for its breadth and depth.
