This valuable historic sundial has been stolen after standing in Yeadon for more than a century.
The artefact has graced the grounds of Hopeville House since before the First World War.
But now thieves have taken the piece of local history which once belonged to renowned Aireborough photographer Ernest Ethelbert Slater.
The pedestal has been left in place and only the valuable sundial, the top part has been taken. It is believed the piece may have been stolen to order.
Mr Slater was a founder member of the Yeadon Photographic Society, and a manager at Manor Mills. He is seen as a major contributor to the photographic history of the area.
He made his home at Hopeville House, which was built in about 1884. The garden was landscaped with glasshouse, pond and other features including the sundial which was produced by a Leeds manufacturer.
