Cimrman's world's smallest lookout tower, Observation tower in Semily, Czech Republic

Cimrman's world's smallest lookout tower is a wooden structure in Nouzov, part of Semily, built by local resident and Cimrmanologist Rudolf Farský Sr. in 2005. Its viewing platform sits 0.1 m below ground level, so visitors look out from a shallow recess rather than climbing. Benches and a period table stand beside it, and the meadow in front of the car park has the letters JC mown into the grass.

The wooden lookout was built in 2005 by local resident and Cimrmanologist Rudolf Farský Sr. in Nouzov, part of Semily. Hurricane Kyrill damaged it and weather wore it down; it was repaired in 2020 and fully reconstructed in 2021, when its surroundings were also adjusted. Since January 2026 the area has been named Návrší Járy Cimrmana.

The tower is named after Jára Cimrman, the fictional Czech polymath invented by Zdeněk Svěrák and Ladislav Smoljak. Its exhibits are Cimrman jokes made physical: a frozen lieutenant of biology Beran unveiled by the cimrmanologist Miloň Čepelka, the skates Cimrman hung up, and a Luxafon phone booth that generates electric current and lights a Christmas tree during the holidays.

The site has a small car park with four spaces, plus a bike rack for cyclists. Larger vehicles and caravans are not advised near the tower and should be left on the public road in Nouzov. Benches and a period table are provided for a snack.

At the site stands a prototype of Cimrman's telescope, made for looking somewhere else entirely. Nearby are a pyramid marking the centre of the world according to Jára Cimrman, a frozen lieutenant of biology named Beran unveiled by the cimrmanologist Miloň Čepelka, and the skates Cimrman hung up on a nail.
