Sievertsche Tongrube

Sievertsche Tongrube is a nature reserve with two distinct sections: a lake in the northern part and open areas in the south. The site features exposed geological layers from the ice age and offers paths for exploring the landscape.

The site was established in 1898 as a clay pit for a brickyard and remained active until the 1950s, with a break during World War II. After closure, the abandoned area naturally recovered and was later protected.

Since its protection in 1986, the site has become important for preserving rare orchid species that bloom in spring. Visitors can observe these plants during walks and see how nature has reclaimed the former extraction area.

The site is accessible via unpaved paths from Eekbalken Street, with additional entrances at Poppenbütteler Way and Gösselkoppel. Access is available anytime, but sturdy footwear is recommended, especially after rain.

The site contains layers from the warm period before the last ice age, exposed by glaciers, offering rare insights into the geological past. These formations make it scientifically valuable for studying the region's climate history.
