Frohburg Castle, Medieval castle ruin in Trimbach, Switzerland.
The remains of Frohburg Castle stand on a hill, featuring remnants of the south wall and foundations of service buildings from medieval times.
The Counts of Frohburg controlled territories between the Aare and Rhine rivers from this castle until their lineage ended in 1367.
Archaeological research since 1970 has revealed evidence of specialized trades, including iron smelting operations and metal processing within the castle grounds.
Visitors can reach the castle ruins through marked hiking paths, with the site remaining open throughout the year without entrance fees.
The castle complex contained three water cisterns, demonstrating advanced engineering methods for water storage in medieval mountain fortifications.
