Castle Hill can be found on New Zealand’s South Island at an altitude of 700 metres next to State Highway 73 between Darfield and Arthur’s Pass. Castle Hill got its name because of the impressive arrangement of limestone boulders there, looking like an ruinous stone castle. Furthermore, Castle Hill limestone was used to build ChristChurch Cathedral in the city of Christchurch. Long ago the limestones provided shelter for Māori food gathering. In Māori the place is called Kura Tawhiti, which means „the treasure from a distant land“ and refers to the precious food source as the kumara (sweet potato) was cultivated there.
