Blinkerdenkmal, War memorial on Landgrafen Mountain in Jena, Germany
Blinkerdenkmal is a war memorial on Landgrafenberg in Jena, made from a limestone block with carved inscriptions. A semicircular wall surrounds the structure and functions as a bench for visitors.
The memorial was inaugurated in 1921 to honor German signal troops who died in World War I. After 1945, military symbols were removed to reflect changing times.
The site honors soldiers who communicated using light signals, a method that was revolutionary before modern radio technology existed. Visitors can still read inscriptions today that remember these pioneers of military communications.
The monument is accessible by hiking trails on Landgrafenberg and offers views over the city. Information panels help visitors understand the history of the signal troops.
The site received a comprehensive restoration in 2021 to mark its 100th anniversary. The work preserved the original structure while applying modern conservation techniques.
