Dufweholms herrgård, Manor house and working life museum in Katrineholm, Sweden

Dufweholms Herrgård is a manor house and working life museum located near Lake Dufweholm that presents itself as an operational museum with a collection of everyday objects and tools from past times. The estate includes accommodation rooms and serves as a venue for meetings and gatherings.

The first säteri was formed in 1484 under the name Stenstorp, when Jönis Geet bought two farms and made them his seat. The first manor house was built in 1622 for Johan Dufva, and his daughter Brita likely renamed the estate Dufveholm after him. From 1921 to 1944 Astrid and Gösta Svinhufvud ran a pensionat here, continued by Ivar and Ester Oscarsson until 1993.

The manor's name comes from Brita Dufva, who likely renamed the estate Dufveholm in honour of her father Johan Dufva. The on-site lanthandel, a century-old village shop, holds one of Sweden's largest collections of enamel and tin signs. The estate museum recreates a barber shop, printing works, cobbler's workshop and pharmacy.

The manor lies just south of Katrineholm, between Duveholmssjön and Djulösjön, with the east facade of the main building standing against the canal linking the two lakes. The grounds hold the manor hotel, the red-painted outbuildings used as a museum and a century-old village shop. The 22 hotel rooms are each named after a former owner of the estate.

The estate's summerhouse by the shore holds wall paintings by Albert Engström, Carl Larsson and Anders Zorn, a detail many visitors walk past on the way to the main building.
