The highest summit on the ridge of the Ruhn Hills, at , is the similarly named
Ruhner Berg ("Ruhn Hill"), which is the second-highest hill in the state of Mecklenburg-Vorpommern and rises clearly above the surrounding area. The summit is accessible via a footpath.
FF Rock Next to the official survey stone on the highest point there is also a
trig point from the first
triangulation survey in Mecklenburg, carried out by
Friedrich Paschen. It is called the FF Rock (
FF-Stein) by
geodesists. The name of this rock comes from the
Frederick Francis II, who gave the order for the
Grand Duchy of Mecklenburg State Survey (
Großherzoglich Mecklenburgische Landvermessung) that took place from 1853 to 1860.
Cyrillic letters have been subsequently inscribed on the rock, for example, on its western face are carved the letters "ГИК" and the year "1945г".
Observation tower In June 1907 the Marnitz Veterans' and Military Society (
Krieger- und Militärverein Marnitz) proposed the erection of a
Moltke Tower. A competition for one did not take place until 1913 however. The project was finally shelved in 1916 due to a lack of materiel and the start of the
First World War; and the donations collected were given to a charity for surviving dependents of those killed in the war. Almost 20 years later a similar project was begun in earnest. In 1933 an observation tower was built on the Ruhner Berg. The wooden tower was replaced in 2000-01 by a 32 metre high brick tower. From the observation deck there is a view of the wooded countryside of the Ruhn Hills, and the vista stretches as far as the
Mecklenburg Lake District, the
Prignitz lowlands and the River
Elbe. The tower was funded by EU donations, donations from firms in the region and private individuals as well as the surrounding parishes, whose coats of arms are displayed on metal shields inside the tower. In addition to its touristic function, the tower is also used as a mobile telephone mast.
Telecommunication tower Since 1992 there has been a telecommunication tower on the southwest slopes of the Ruhner Berg. It is 91 metres high, made of reinforced concrete and owned by
Deutsche Funkturm. (location: ). == Hills ==
