11. Rock of Ages
200 years ago, when the Middleton Estate was being transformed into a water park, the science of geology was in its infancy. No-one knew where rocks came from and how long they had existed. Then 19th century geologists realised that the rocks of North Wales held the secrets of Earth's geological history. This is reflected in the names of Silurian, Ordovician and Cambrian to describe geological time zones: the Silures and Ordovices were Welsh tribes, and Cambria is the Roman name for Wales.
The 'Rock of Ages' tells the story of Welsh geology using stones donated from all over Wales. As you walk up the Broadwalk, the rocks form a sequence from youngest to oldest, dated in millions of years. They show the importance of geology in determining the shape of our landscape and the soils on the land.
