Parkhöhle Weimar

Park Cave, Weimar
The Park Cave is an underground tunnel system in the park on the Ilm. It is located twelve meters below the ground between the steep slope to the Ilm and Belvederer Allee. A staircase near the Liszt House leads down to the tunnel, which ends at the so-called "needle's eye", an artificially created rock gate on the Ilm.
History
The Park Cave owes its existence to Duke Carl August's desire for his own brewery. Between 1794 and 1796, a tunnel around 500 meters long was built in the park on the Ilm to drain the process water of the planned brewery. After the plan to build a brewery was abandoned, the tunnel was used for sand and gravel mining between 1797 and 1815. A complex system of passageways and tunnels was created. Towards the end of the Second World War, part of the complex was converted into a bunker. This area now houses the Park Cave Museum.
Permanent exhibition: Park Cave Experience
Through time and climate
The permanent exhibition tells the story of the park cave: created in Goethe's time, unused for decades, converted into a shelter towards the end of World War II, it has been accessible again since 1997, interrupted by a pandemic and a comprehensive renovation.
