Is NO LONGER emptied! No more money for NATURE. Volunteers from IVN Elsloo built a wooden walkway near the Kromme Dijk in the first week of January '26. This makes the popular hiking trail along the Hemelbeek accessible again. This is a temporary solution pending definitive measures by Staatsbosbeheer, the owner of this forest area. They will also be consulting with the municipality of Stein and IVN again soon. Unfortunately, Waterschap Limburg is not contributing to a solution because they no longer empty the sand trap, causing the area to suffer not only from waterlogging but also to fill up with sand and silt.

In the past, people fetched their water for household use here, and in practice, the 'pötje' was mainly used to rinse laundry that was washed at home. For this, they had special permission from the lords of the castle to enter the forest area. At a height of 60 cm, a pipe was driven into the forest wall, so people could collect the water more easily in buckets. In the 1950s, the water pipeline was built in Terhagen by the municipality of Elsloo. The 'Terhagerpötje' then fell into disuse and disrepair. In 1988, it was reopened after restoration. The neighborhood association Terhagen had campaigned for this. Meanwhile, decay has set in again, and the designation 'Terhagerpötje' is a memory.

The Elsoër forest is the steepest slope forest in the Netherlands! All sorts of spring streams flow through the forest. This special ecosystem is home to rare forest plants and aquatic animals such as newts and frogs. This piece of nature is so special that it has been included as a protected area by the European Union.

This sand trap catches the sand and silt carried by the fast-flowing water. It prevents the stream from silting up and causing flooding.

INFORMATION BOARD Terhagerpötje Spring THIS IS THE POWERFUL SOURCE IN THE TERHAGERBERG NEAR THE LITTLE BRIDGE ON THE SLOPE. THE RESIDENTS OF TERHAGEN, CATSOP, AND ELSLOO DERIVED THEIR DRINKING WATER FROM THIS SOURCE AND DID THEIR LAUNDRY THERE. Part of the Terhagerberg was the Santeberg (sand hill). Until well into the last century, residents still dug sand here near the Terhagen spring stream. HISTORIC PATHS The villagers could find the spring by following the footpath from Terhagen and walking under the small bridge. Elsloo residents reached the spring via the historic road from Kaakstraat. By using these historic paths, the population could still reach the spring without entering the noble estate (an area forbidden to the villagers). Potje is an old word for spring. CEMETERY Elsloo once had a cemetery intended solely for the burial of Jews, specifically for one family: the Manases family. In the seventeenth century, the lord of the castle of Elsloo granted this family permission to live in Elsloo and practice their trade as butchers. One of the stipulations and conditions was that they could bury their dead at the Santeberg, not far from Terhagerpoga. Although we know for certain where this location was, it is assumed that the dead were buried on the hill at the entrance to the park at the foot of Terhagerberg. In 1836, the last descendant of the Manases family left Elsloo, and the cemetery was incorporated into the park. Source: Terhagerpotje ® Bune Kiseg Bunnik, HM Bronbeekje from Terhagerpotje

In the castle forest of Elsloo and elsewhere in the region, many springs originate, you can see the water flowing from the slopes here and there. And you can see the result in nature and even in some places in Elsloo where people have tried to use springs in houses in the old center. Here, near Terhagen, such a spring originates that can be reached via a small viaduct. And that spring was given the name Terhagerpötje (Terhager well). Terhagen is one of the two hamlets of Elsloo (the other is Catsop). On a sign you can read that the Terhagerpötje was used in the past by people to rinse the laundry washed at home and that they had permission from the lords of the castle to do so. A pipeline was even built to collect the water. You can read this whole story and more at https://kleinemonumentenstein.nl/monumenten/diversen/terhagerpotje
