Cretaceous sea

It teemed with flora and fauna such as sea grasses, corals, fish, sharks, and mosasaurs. The skeletons of these animals formed a thick layer of limestone over millions of years. When the sea later dried out, these yellow limestone layers of Cretaceous bedrock were left exposed. They are still clearly visible in the ENCI quarry and caves of the St Pietersberg nature reserve.

ENCI quarry

Today, the ENCI quarry is an industrial heritage and natural beauty site in one. In 1926, the Dutch cement company began excavating limestone from St Pietersberg hill to make cement. The marl mines were closed in 2019. What remains is a unique canyon landscape where you can walk among the grazing sheep and goats. The trail is open each day from 1 April to 1 September between 8:00 AM and 8:00 PM. From 1 September to 1 April, it is open each day from 9:00 AM to 5:00 PM.
