Björkborn Manor, Museum of Alfred Nobel in Karlskoga, Sweden.

Björkborn Manor is a white manor house completed in 1814, with older parts from 1694, in Karlskoga. It houses the Nobel Museum with exhibitions on Alfred Nobel and the Nobel Prize, and preserves much of his private library. The manor stands in a park bordered by the Timsälven river.

Björkborn was founded as an ironworks in 1639 by Mårten Drost, a Dutch-born bailiff in Karlskoga, and remained in operation until 1901. The current manor was rebuilt in 1814 on a house originally raised in 1694. Alfred Nobel acquired the estate in 1894 through Bofors-Gullspång and lived there until his death in 1896.

The manor keeps a large part of Alfred Nobel's private library, with original volumes still on the shelves. Since 1978 it has housed the Nobel Museum in Karlskoga, which shows exhibitions on Nobel's life and arranges guided tours, some of them dramatized. In Nobel's old stable, the meeting place Mötesplats Alfred Nobel now hosts concerts, theatre tours and lectures.

The manor stands on Björkbornsvägen 10 by the Norrleden road, within a park bordered by the Timsälven river to the west and south. Björkbornsbron bridge, opened in 2022, links the estate with central Karlskoga. The museum occupies both the manor and Nobel's laboratory just north-east of the grounds, and the old stable now holds a meeting venue.

The laboratory building where Nobel conducted experiments with explosives and synthetic rubber still stands on the property and functions as an exhibition space. Visitors can see the actual tools and equipment he used in his research work.
