Sturefors Castle by Lake Ärlången belongs to the Bielke family. It is a three-storey building with wings, constructed in 1704 by Tessin the younger for Carl Piper. The castle is known for its 1700s interior. You can only see Sturefors Castle from the outside, but it is worth a visit for the fine English Park that was created during the 1700s with a magnificent mirror pond, and the nature reserve which lies in the grounds of the old castle. https://visitlinkoping.se/en/do/attractions/castles-and-manors/sturefors-slott
