The Eichsfeld village of Lengenfeld unterm Stein, which was first mentioned in a document in 897, lies in the romantic valley of the Frieda river, which rises near the nearby Zella monastery and makes the village an ideal vacation and travel destination for tourists and hiking enthusiasts. Many well-preserved and carefully restored houses, which were once built in the half-timbered style, still characterize the image of the predominantly Catholic village today.

The village is surrounded by high mountains, which give the landscape a special character with their deciduous and coniferous trees. Lengenfeld unterm Stein is characterized by three landmarks that greet visitors from afar. High above the village is Bischofstein Castle, built in 1747/48 in the Baroque style, which has always attracted the attention of many visitors. The historic building is currently being gradually restored. Today, a care center is located within its walls.

Another attraction is the neo-Gothic parish church, which was built in 1882 and still calls many Christians to prayer today. At Christmas time, the church is a jewel of the region with its nativity scene filling the entire chancel.

However, the real landmark that has made this town famous beyond Germany's borders is the huge railroad viaduct. With a height of 24 m and a total length of 240 m, it spans the entire town. Built back in 1875, it is still a symbol of historical architecture today. The viaduct, which was created as part of the so-called Kanonenbahn, is now used by trolleys and is an attraction for Lengenfeld and the region with around 30,000 visitors a year. 

Parallel to the trolley route, the Kanonenbahn cycle path with a total length of 28 km was inaugurated in October 2019. The special feature of this cycle path is its route, far away from the road network, with historic buildings in one of the most beautiful natural areas of the Eichsfeld. It leads through five tunnels and over four bridges. The Cannon Railway Cycle Route completes the connection to the Leine-Heide Cycle Route, the Unstrut Cycle Route and the Werratal Cycle Route.

The renovated train station is a real gem. The lovingly furnished rooms, which reflect the typical character of a railroad station, offer space for around 100 people. It also houses the Kanonenbahn restaurant.

Hiking trails, vacation apartments and private guest rooms attract tourists and guests, as does the newly renovated outdoor pool, which is very popular in the summer months. Horse lovers can explore the natural surroundings on extensive bridle paths. Due to its extremely scenic location, the municipality is focusing its development on the further expansion of the tourist infrastructure and a balanced relationship between trade, crafts and services.
