Tannegg Castle Ruins

Highlight • Castle

There is not much left of the castle ruins, but the wall is still impressive and, above all, the path over the Tannegger Grat is an absolutely beautiful rooty and cool ridge path. Is worth a trip!

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

Castle / Castle ruins Helfenberg, Gossau SG The castle was probably built in the first half of the 13th century. It was a residence of the Gielen von Glattbrugg family. In 1244, the castle was part of the foundation of the knight Rudolf Giel von Glattbrugg for the Magdenau monastery. The family continued to manage the castle - probably as a fief - and in 1341 the castle was rebuilt by the family. For knight Rudolf II Giel von Glattbrugg in 1244, who had founded the Magdenau monastery, the estate on which the previous building, the "castrum Helfinberc", had once stood, was part of his foundation. The castle was apparently already dilapidated at that time. From then on, the imperial monastery had servants manage Helfenberg. By 1388 at the latest, the Princely Abbey of St. Gallen was the owner of the castle complex. In 1401 it was besieged by the surrounding farmers, which ultimately led to the Appenzell Wars, in which the castle was completely destroyed in 1407. The complex fell into disrepair and then largely slid into the Glatt ravine. This was their last act after the Appenzell Wars. The castle complex, destroyed by the rebellious farmers, was then left to decay. The first excavations were carried out between 1935 and 1937. In 1939 the ruins came into the possession of the Oberberg cooperative in Gossau. Since 1964/1965 the ruins have been secured and preserved to their current state. The ruins are located not far from the Glatt gorge and not far from the Kolumbanshöhle. Access is only recommended on foot and with hiking equipment.

A beautiful, larger ruin, but more of a castle because no remains of the wall are visible. Nevertheless, an imposing castle hill and, above all, a large moat.

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 Tanneggergrat S3-4 (from the ruins of Tannegg) is completely unsuitable to life-threatening for bikes (downhill), uphill anyway.
