Maják Járy Cimrmana, Observation tower in Kořenov, Czech Republic.

Maják Járy Cimrmana is a wooden observation tower in Kořenov that rises approximately 24 meters and blends modern design with lighthouse-like features. The structure serves both as a viewing point and a cultural museum housing exhibits about the fictional character Jára Cimrman.

The tower was built by the architecture group Huť Architektury led by Martin Rajníš in the mountainous region of Kořenov. The project emerged as part of developing the area as a destination for mountain visitors and cultural tourism.

The tower and the museum beneath it are named after Jára Cimrman, a fictional Czech inventor and artist invented by Zdeněk Svěrák and Ladislav Smoljak; the German text wrongly calls him a writer. Access to the viewing platform leads through the museum, whose exhibits present his imaginary life and work.

The tower sits at the intersection of several hiking paths and is accessible throughout the year, with connections to both the Krkonoš and Jizerské mountain ranges. Access is straightforward for visitors already traveling on local trails.

The tower and the Jára Cimrman museum beneath it cost about 4 million Czech korunas and were financed by the owners of the neighbouring guesthouse U čápa without European subsidies. Access to the viewing platform leads through the museum. The 115 steps are made of pine wood.
