Rinkesta, Heritage château in Eskilstuna Municipality, Sweden.

Rinkesta is a château in Eskilstuna Municipality positioned between two lakes, featuring traditional Swedish building forms and formal gardens around the grounds. The buildings display multiple construction styles that were added or modified during the time of different owners.

The château came into the hands of Privy Councillor Gustaf Gabrielsson Oxenstierna in 1594, who started its development. After a fire in 1698, it underwent major rebuilding and remodeling under later owner Thure Leonard Klinckowström around 1775.

The name Rinkesta is first documented in 1379, when Bo Jonsson (Grip) donated one öresland there to Strängnäs Cathedral. Above the entrance portal hangs a cartouche with a German inscription inside a laurel wreath. The year 1664 may mark the completion of the building.

The main building stands south of Norrsjön and north of the drained Sörsjön in Ärla parish. The castle itself was unoccupied in the 2010s, and the middle floor was converted into a private residence between 2017 and 2020, so it is not a public museum. The estate is privately owned; check access before travelling.

The entrance side is dominated by a tall stair tower topped with a lantern, and this tower is the element that still recalls the original 17th-century building. Erik Dahlbergh depicted the house in his Suecia work in the 1680s, when it had ornamental gables and spires and stood within a high stone wall.
