In the tenth episode, the media center in Salzgitter-Salder is on the move.
Most people know Salder Castle as a cultural, educational and event location. But the castle also hides secrets that can easily be overlooked – in its wall.
Renate Vanis, Salder’s local caretaker, reports on the small fossils that can be found in the wall around the castle. The petrified stems of the so-called sea lilies are also called trochites. By the way, sea lilies are not plants, but echinoderms and are related to sea urchins and starfish.

When the sea lilies died during the Upper Muschelkalkzeit approx. 230 million years ago, they sank to the sea floor and formed a rock layer, which is also called trochitic limestone.
This trochitic limestone was later mined and broken in the ducal quarries in the Salzgitter ridge. Some buildings, such as Salder Castle, were built with this building material.

Incidentally, there are two circular hiking trails on this subject in the Salzgitter ridge, they lead through the beech forests of the nature reserve. These geopaths cover a period of more than 150 million years, from the limestones of the shell limestone to the deposits of the Cretaceous period. There you can not only enjoy nature and discover fossils, but also learn a lot about Salzgitter.
