Friedenstein Castle in Gotha was surrounded by one of the strongest Baroque fortifications in central Germany - the casemates. The fortifications, which today lie beneath the palace park, have remained unchanged for more than 350 years and are in very good condition, further enhancing the architectural and historical significance of the imposing palace complex.

The casemates can be visited on an approx. 300 meter long underground tour. There are embrasure chambers, rifle galleries, rear defenses, connecting passages, elevator shafts and much more to discover.

Duke Ernst the Pious had the castle built between 1643 and 1654 on the foundations of the former Grimmenstein. The foundation stone for the protective structure was laid in 1655. It never had to prove its effectiveness. From 1772, the fortifications were removed above ground and the ramparts and ditches were leveled to complete the castle park.

The temperature in the casemates is a constant 8 degrees all year round. There are daily public guided tours with advance booking.
