The Lörmecke tower is an approximately 35 m high observation tower in the Plackwald in the Sauerland . In the Arnsberg Forest Nature Park , it is located in the wooded area of the city of Warstein in the North Rhine-Westphalian district of Soest on the Plackweghöhe .
Geographical location
The Lörmecke tower is located in the Plackwald natural area , part of the North Sauerland Oberland , in the “Warsteiner Wald”, the eastern part of the Arnsberg Forest Nature Park. It is located about 3.2 km north of Eversberg (northeastern part of Meschede ), 5.7 km south of Warstein, 2.8 km east-northeast of the Stimmstamm pass ( 541.1 m above sea level ) and 500 m (as the crow flies ) west-southwest from the headwaters of the Glenne tributary Lörmecke . It is not quite halfway between the Niekopf ( 550.4 m ) in the northwest and the Warsteiner Kopf ( 556.9 m ) in the southeast. A few meters south of the tower, the border runs from the Soest district to the neighboring Hochsauerlandkreis .
According to the German map , the Lörmecke tower is surrounded by conifers, directly north of the altitude 581.3 m (about the highest point of Warstein) and about 35 m north-northeast of the Plackweghöhe 581.5 m (including the highest point of the Arnsberger Wald nature park) at 580.9 m . About 100 m east of the tower, at the foot of which there are several benches, the Hessengraben runs roughly in a north-south direction .
Laying of the foundation stone and inauguration
The laying of the foundation stone and the christening of the observation tower with the name “Lörmecke-Turm”, as the inscription on the foundation stone reads , took place on August 16, 2007. On June 7, 2008, around 1,000 hikers walked to the tower as part of guided star hikes, the individual routes of which began in Eversberg, Meschede and Warstein, in the presence of some "officials", such as the mayors of the surrounding cities, District Administrator Eva Irrgang and the North Rhine-Westphalian Environment Minister Eckhard Uhlenberg to attend the inauguration of the building. Afterwards, visitors to the tower climbed to the viewing platform for the first time . A small party was organized on site so that food was also provided. Between the laying of the foundation stone and the inauguration (time span almost 10 months), including, for example, weather-related breaks, there was a total of about 5 months of construction. The building owner and owner of the Lörmecke tower is the Arnsberg Forest Nature Park Association.
Tower description
The static elements of the cladding-free tower construction consist of 144 Douglas fir trunks that are crossed, one above the other and one next to the other , which were felled in local forests and are each 12 m long. During the construction, 3 trunks were placed on top of each other and of these now 36 m long round timbers, 24 each for the outer and inner layers with 15 ° offset on the circular shape of the tower base. Towards the top of the tower, the trunks are arranged at an 82 ° incline to the horizontal and rotated by 90 °, which results in the tapering in the center of the tower. The round timbers are connected at 288 crossing points by screw connections with internal and external steel rings to ensure the stability of the tower. The entrance to the tower was created by omitting a foot point with the 2 adjoining round timbers up to the next higher crossing point. Inside the tower, a steel spiral staircase with 204 steps leads between the trunks over two intermediate landings up to the viewing platform. The diameter of the base and tower head is about 7 m, in the middle about 5 m.
The tower foundation consists of around 144 m³ of reinforced concrete in the ground. With its overall height (35 m), the Lörmecke tower was 9 m taller than the Küppelturm (26 m), which was also located in the Arnsberg Forest Nature Park until October 2017 and stood near Freienohl on the Küppel mountain ( 422.6 m ).
The tower shape resembles a single-shell hyperboloid construction ; it is falsely as translation - paraboloid referred. Towers with a similar construction include the Jübergturm ( Hemer , North Rhine-Westphalia) and the Kobe Port Tower ( Kobe , Japan).
purpose
When an appraisal was drawn up in 2003 due to the planning intentions for the hiking trail Sauerland-Waldroute , it was recognized that in the Arnsberg Forest nature park there are large areas of forest facing few vantage points ; therefore a lookout tower was required and finally the Lörmecke tower was built. Since 1935, the Lörmecke waterworks have been promoting drinking water from the groundwater of the local "Warsteiner mass limestone". The tower stands for the gift of nature, the permanent supply of the people in the southern Soest district with vital water .
Construction costs and sponsors
The tower construction cost around € 450,000 . About a third of this was paid by the North Rhine-Westphalian Ministry of the Environment , other parts of the Soest and Hochsauerland districts, the cities of Warstein and Meschede, the Warsteiner Brewery , the Forest and Wood Agency, the “Warstein-Touristik e. V. “as well as the Lörmecke waterworks, which acted as the main sponsor of the project; therefore the building is called the “Lörmecke Tower”.
Possibility of viewing
From the top viewing platform (approx. 615 m ) of the Lörmecke tower, which is located far above the treetops, you can enjoy a beautiful panoramic view (360 °) over the Arnsberg Forest Nature Park and - looking clockwise from the north - to the Haarstrang in the Westphalian Bight , to the Teutoburg Forest and Eggegebirge and across the Ruhr valley to the Rothaargebirge and Lennegebirge .
hike
The Plackweg , a former trade route and today's hiking trail, passes the Lörmecke tower about 200 m to the southwest in a west-east direction. The Sauerland Forest Route , a hiking trail running from Marsberg through the Arnsberg Forest Nature Park to Iserlohn , leads past the tower, which is the landmark of this hiking trail. In addition, the 7.5 km long “Lörmecke Tower Path” runs to the tower.
