Cimrman's world's smallest lookout tower

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

Cimrman's world's smallest lookout tower is an observation structure in Semily that measures exactly zero meters in height, making it officially the smallest of its kind. Despite this peculiar dimension, it sits at an elevation of about 529 meters and offers views across the local landscape.

The tower was built in 1917 when local residents contributed materials and labor, while Jára Cimrman financed the project from his regular income. This community effort resulted in the unique structure that stands today.

The structure bears the name of Jára Cimrman, a legendary figure in Czech culture who is said to have worked with Gustave Eiffel on the Paris tower project.

The tower is accessible around the clock without restrictions, and convenient parking is available near the junction of path and street 260 in Semily. Visitors can arrive anytime and explore the site freely.

The structure features a telescope for observing local landmarks, including the peculiar Cimrman giant mushrooms located south along road 260. These odd formations are a rare geological feature of the area.
