The landscape you see here was created about 250 million years ago at the turn of the Unterrotliegend to the Oberrotliegend. At this time there was intense volcanic activity in the nearby area. Molten masses, so-called magmas, rose from the depths of the earth's crust. They penetrated the overlying rocks or they reached the surface of the earth, where they quickly cooled and solidified. Chimneys opened from which ash and tuff were ejected. The Evangelical Church stands on a so-called volcanic vent, a vertical ascent channel of volcanic products from the earth's interior. The mass has solidified at the earth's surface and has resisted subsequent erosion, dissecting mounds.
The extinct volcanoes include the Welschberg 336.3 meters above sea level (transmission mast), the Lemberg 420.8 meters above sea level, the Gangelsberg 340.6 meters above sea level and the Heimberg 302.7 meters above sea level.
The Heimbergturm is a 29 m high observation tower on the 302.7 m above sea level. NHN high Heimberg between Schloßböckelheim and Waldböckelheim in the Naheland (Rhineland-Palatinate). It was built in the spring of 2008 in the manner of a wooden framework and has a square floor plan. The cornerstones consist of 85-year-old, natural Douglas fir trunks from the Soonwald near Mengerschied and are braced crosswise with metal braces. A left-hand wooden staircase serves as the staircase, which leads over 144 steps and 15 intermediate landings to the covered viewing platform.
The tower is primarily used for tourist purposes to provide a view of the Soonwald-Nahe Nature Park.
On the covered platform of the tower you can see the small Feldberg near Königstein im Taunus, the Donnersberg in the Palatinate Uplands and the Erbeskopf near Idar Oberstein on a clear day.
