WORK to reinstate important features of the designed landscape of one of North Yorkshire’s greatest houses has entered its second phase.

It follows the successful restoration of the Castle Howard estate’s central lime avenue earlier this year - which has since seen the avenue removed from the Historic England Heritage at Risk register.

The second phase will focus on the restoration of the 18th-century obelisk ponds which span the avenue.

Over the years their original clay liners have degraded and they are no longer watertight - resulting in unsightly dry basins where the pools of water should be.

Nicholas Howard said: “Water is a fundamental part of our designed landscape and the ponds and lakes which dot the estate are an integral part of the original 18th century garden plans.”
