Desná Dam, Historical dam ruins in Mariánská Hora, Czech Republic.
The Desná Reservoir features a control tower and drainage channel amid forest surroundings in the Jizera Mountains.
Built between 1912 and 1915, the dam collapsed in September 1916, causing a catastrophic flood that resulted in 67 fatalities.
The memorial site includes twelve wooden sculptures along the path and educational panels narrating the engineering history of Czech water management.
While vehicles cannot access the dam directly, multiple parking areas connect to walking trails leading to the remaining structure.
The ruins now serve as a winter habitat for protected bat species and stand as the largest disaster in Czech water management history.
