The palace was built in 1671-1672 by architect Mathias Spieler for the Dutch-born Swedish military officer Thomas van der Noot.
[1] The facade has pilasters and festoons and the middle part is decorated with mermaids in the sandstone.
Architects for the renovation and expansion in 1903-1910 were Isak Gustaf Clason and Agi Lindegren.
Jahnsson was hit hard by the Kreuger crash in the early 1930s, in which he was stripped of his wealth and forced to leave the Van der Noot Palace and auction off most of the collections.
The remainder of Jahnsson's collections from Van der Nootska, which mainly consisted of the Stockholmiana Collection, were donated in 1942 to the Stockholm City Museum by Axel Wenner-Gren, who in February 1938, had bought the Van der Nootska Palace.
