Cvilín, Observation tower and cultural monument in Krnov, Czech Republic.

Cvilín, also called Liechtensteinwarte, is a cylindrical stone tower 29 metres high on the northern slope of Přední Cvilínský kopec at 436 metres above sea level, southeast of Krnov. Built in 1902–1903 to Ernst Latzel's design, it has a single open viewing gallery reached by 144 steps; its original 35-metre height included a small turret removed in post-war repairs.

A tower committee was founded in 1899 under Johann Kienel, head of the town forests and treasurer of the MSSGV's Krnov section. A collection raised 10,000 crowns, of which Prince Johann II of Liechtenstein gave 2,000; Ernst Latzel designed the tower and directed a year of construction. It opened in 1903 as the Liechtensteinwarte, costing 11,300 crowns, was damaged in World War II, closed to tourists in the 1960s when broadcasting antennas were mounted, and is listed as a monument.

The tower is named Liechtensteinwarte after Prince Johann II of Liechtenstein, who gave 2,000 of the 10,000 crowns collected for its construction. The Moravian-Silesian Sudeten Mountain Association (MSSGV) built it, and its Krnov section chairman Johann Kienel led the fundraising committee from 1899.
