Lindholmen Castle, Medieval castle ruins near Lake Börringe, Sweden

Lindholmen Castle is a medieval fortification in southern Scandinavia whose remains appear today as an earthen mound with scattered stones on a raised hill. The structure originally featured double moats and reinforced defenses built to control the surrounding landscape.

The fortress began as a private stronghold and came under royal control in 1339 when King Magnus Eriksson took possession, strengthening its role as a defensive structure. Later it was used to confine a defeated Swedish monarch.

The name Lindholmen refers to the hill by lake Börringe where the castle stood. In 1395 Queen Margaret I of Denmark held peace talks here with the deposed Swedish king Albrecht von Mecklenburg; the meeting lasted 16 days and so many participants came that tents were pitched on the castle grounds. Albrecht had been held prisoner at Lindholmen for nearly seven years after his defeat at Falköping in 1389.

The site is accessible via marked walking paths through the surrounding countryside with informational signage explaining the medieval layout. The elevated position offers clear views across the marshlands and waterways that surround the ruins.

Albrecht von Mecklenburg was held at Lindholmen for close to seven years after his defeat at the Battle of Falköping in 1389, while Margaret I ruled Sweden in his place. The 1395 talks on the castle grounds lasted 16 days and drew so many participants that tents had to be pitched to house them.
