Grottenstein castle ruin
Grottenstein castle ruin, Castle ruin at Mount Calanda, Haldenstein, Switzerland
The Grottenstein castle ruin stands at the foot of a rock face, featuring a remaining 20-meter-long section of wall built under a rocky cliff.
Built around 1180, the fortress remained undocumented until 1672 when records first mentioned it as Crottenstein, referring to its already ruined state.
The structure represents a cave castle design, demonstrating medieval defensive architecture through its strategic placement and fortified entrance across a natural cavern.
Visitors reach the ruins through a 2.9-kilometer circular hiking trail from Haldenstein village, climbing 268 meters in elevation over approximately 75 minutes.
A natural spring within the castle cave suggests its potential role as an emergency shelter, while the name derives from 'Chrott,' meaning toad in German.
