Built after 1200 by the Counts of Toggenburg, it began to decay in 1468. The preserved foundation walls cover a fairly large area.

Anyone who has made it to the castle, which today only consists of a tower, should add another hour: a simple hike through the Bätzimatt der Linth nature reserve or along the Linth Canal is a real stunner! Further information: https://www.teddy-b.ch/excursions/baetzimatt-tuggen-sz-linth-ahoi/

Very interesting ruin, as Tanja and Heloks already described. But the sight and the view must be earned, the ascent and descent are quite steep.

The castle is right on the Linth and a country inn was built next door. Is privately owned.

Additionally, Schloss Grynau and country inn, a medieval low castle with its original 13th-century tower still preserved, is also worth a visit.
Iberg Castle, also known as Yburg, was built after 1240 to secure crucial pass crossings over the Ricken and Laad, protecting the Abbey of St. Gallen's assets.
