Lotsenturm Thiessow, Communication tower with observation platform on Rügen, Germany

Lotsenturm Thiessow is a 34-metre steel lattice tower on the 35.6-metre Lotsenberg southeast of Thiessow on Rügen. It was rebuilt in 2003 in the style of the 1909 pilot watchtower, with a covered observation platform at 13 metres. At its foot stands the 1854 brick pilot watchhouse on a fieldstone base.

The pilot watch at the foot of the tower dates from 1854, built of brick on a fieldstone base and first roofed with reed, later with tiles. A wooden upper storey added in 1892/93 proved inadequate, so a steel-framed, wood-clad pilot tower was erected beside the upper watch and inaugurated on 8 November 1909. It served until about 1977, decayed, and was rebuilt in 2003.

The 1854 brick pilot watchhouse at the foot of the tower now holds an exhibition on pilotage in Thiessow and the Southeast Rügen Biosphere Reserve, opened in April 2000 after restoration by the spa administration and reserve staff. Inside, a light blue paint scheme recorded in older accounts was reapplied; the exhibition was revised in 2009.

The 13-metre-high covered viewing platform is accessible at any time, while the exhibition in the tower and the former pilot watch house next to it is open daily from April to October. The tower stands southeast of Thiessow on the 35.6-metre Lotsenberg hill, close to the Südperd cliff above the Baltic Sea.

On clear days, visitors can see multiple islands and coastal areas at once from the top, including Usedom and Greifswalder Oie. This wide view across water and land helps people understand how this region sits geographically.
