 Since this type of stone is not local it was determined as having been transported there from Shap in Cumbria by glacial action during the last ice age.In 2015, to celebrate the 200th anniversary of the publication of the geological map of Britain by William Smith, a mosaic map was commissioned for the Gardens from artist Janette Ireland which shows the geological strata of Yorkshire in pebbles of the corresponding stone.As well as being a popular recreational space for both residents and visitors, the gardens are the venue for special events such as open-air theatre and music performances.
