Louis Jean Desprez

He studied architecture and was awarded the Great Prize of the Académie royale d'architecture in 1770.

His first task there was the decorations for the new opera Gustaf Wasa (with a libretto authored by the King in collaboration with Johan Henric Kellgren and music by Johann Gottlieb Naumann).

[4] [5] [2] As an architect, Desprez designed in a monumental, neoclassical style influenced by his study of Greek and Roman ruins in the south of Italy and in Sicily.

The smaller "royal pavilion" which stands at Haga was built by architect, Olof Tempelman.

[2] [3][6] His most significant completed project was the conservatory building in the new botanical garden in Uppsala, inaugurated after his death on May 13, 1807, the 100th anniversary of Linnaeus's birth.
