The palace and its gardens were located on the site where the first church in the area had been erected by Saint Eskil.
A plan drawn by Jean de la Vallée in 1658 for a new palace north of Eskilstunaån existed but was never realised.
[2] A fire in 1680 destroyed most of the upper levels of Eskilstuna House, only sparing the basements, which remained in use as a local prison.
The palace was never rebuilt; instead, the seat of the county administration was permanently moved to Nyköping in 1683.
[1] Presently, a school named after the palace and a cemetery belonging to Eskilstuna Parish are located on the site.
