The first version of Huvudsta Gård, the main building (corps de logi), was constructed in 1650 by Rear Admiral Gustav Otto Stenbock. It was a two-story wooden house with two wings. He also established a baroque garden and Huvudsta Avenue. From the 1690s to around 1747, Huvudsta Gård was leased out and used for various purposes, including as a tavern.
There are documents preserved from 1706 that mention there was an inn at Huvudsta Gård. It was operated by Master Anders Månsson. On January 4, 1710, it was noted in the newspaper that the ice was safe, the innkeeper was present, and they welcomed all gentlemen(!) to the inn.
In 1750, merchant councillor Anders Plomgren purchased Huvudsta. He demolished the old, dilapidated buildings and constructed new ones. Huvudsta Palace now resembled Drottningholm, with a two-story main building, the current wings, an orangery, and a well-planned garden in a grid pattern.
After Anders Plomgren, his son Carl Anders Plomgren took over. However, he had to flee the country in 1782, and the estate was taken over by his nephew, Claes Fredrik Horn.
The conspiracy involving the Gustav III assassination took place here, in the old castle, in 1792. Claes Fredrik Horn was one of the chief conspirators. Among those involved were also Jacob Johan Anckarström, Adolph Ribbing, Carl Pontus Lilliehorn and Carl Fredrik Pechlin. Anckarström was chosen to carry out the murder which he did - he shot the king at the Stockholm Opera on March 16. However, Gustav III did not immediately succumb to his gunshot wounds. Initially, it was thought that the injuries were not severe, and he would not need surgery. However, complications arose, including the formation of abscesses, high fever, and gangrene. The king passed away on March 29 and was later buried in Riddarholmen Church.
Claes Fredrik Horn was sent away to Copenhagen, leaving behind his wife and a son at Huvudsta Gård. The son, also named Claes Fredrik, took over the estate but eventually sold it.
In 1817, the Wibom family arrived at Huvudsta Gård. Mr. Wibom was a brass founder and made money manufacturing uniform buttons and weapon details in gold metal during the Sweden-Russia War in 1809. During this time, estate buildings were constructed, including tenant houses, a barn, stables, outbuildings, a distillery, and more.
In 1834, the old castle was moved to a hill a few hundred metres away, towards Huvudsta subway station, and now belongs to the Swedish Church. In 1836, Hufvudsta Gård's third and current corps de logi was completed. It was built in the Russian Empire style by the Russian ambassador Peter van Zuchtelen. The lantern at the top became a banquet hall with views in all directions.
Today, the building is known as the "New Castle." The Wibom family still owns the estate and resides in the wings. However, the main building has been leased as offices since the 1950s. In 1999, Hufvudsta Gård Conference AB moved into the premises.
