Adamsberg, Building in Norrtälje Municipality, Sweden.

Adamsberg is a manor just outside Rimbo in Stockholm County, formerly called Framskälby and renamed after the councilor Adam Horn af Ekebyholm (died 1778). A new corps-de-logi was built in 2016 on the spot of Adam Horn's old main building, which had burned down.

Adamsberg was long called Framskälby and took its present name from the privy councillor Adam Horn af Ekebyholm, who died in 1778. It was owned by admiral Nils Göransson Stiernsköld and from 1626 by Bengt Bengtsson Oxenstierna, then by the Horn family, and was joined with Ekebyholm in the same parish. In 1936 it was bought by baron Magnus Lagerbielke, and since 2016 it has been owned by his son, Count Gustaf Lagerbjelke.

The name Adamsberg comes from the councilor Adam Horn af Ekebyholm, who died in 1778; the estate was previously called Framskälby. The Lagerbjelke family connection shows in the spelling: Magnus changed Lagerbielke to Lagerbjelke when he became a count after 1973.

Adamsberg lies just outside Rimbo in Norrtälje Municipality, Stockholm County, and is reached by local roads from Rimbo. It is a private estate, so the grounds and buildings are not open to the public; the manor is best viewed from the public road. The present corps-de-logi dates from 2016.

The manor was long called Framskälby; it took the name Adamsberg from the councilor Adam Horn af Ekebyholm, who died in 1778. The old main building burned down, and in 2016 Gustaf Lagerbjelke had a new corps-de-logi built on the same spot, on the initiative of his son Johan Lagerbielke.
