further political advancement. After leaving Sheffield, Mary was taken to Wingfield Manor in Derbyshire by her new gaoler, Sir Ralph Sadler, and then to Tutbury. From there she went to Chartley Manor in Staffordshire, where she became involved in the Babington Plot. Duke of Norfolk After Sheffield Manor fell into the hands of the Duke of Norfolk, it was neglected, sold to tenant farmers, and largely dismantled in 1706. Some remaining walls and a window were removed to the grounds of Queen's Tower in Norfolk Park by Robert Marnock in 1839. In 1953 the Duke of Norfolk Estate leased the site to Sheffield City Council for 999 years. "Restoration" plan In 2004, the building featured on the BBC TV programme Restoration and was the subject of a National Lottery funding bid to convert it to a heritage centre and traditional farm. Green Estate, which was established by the Manor and Castle Development Trust and Sheffield Wildlife Trust, received £1.25 million from the Heritage Lottery Fund to restore the Turret House and develop the site as a visitor attraction. Visitor attraction The Sheffield Manor Lodge visitor attraction includes the Turret house, Tudor grounds, Discovery Centre, and Rhubarb Shed Cafe. The Turret House is open to the public every Sunday between April and September, in Sheffield school holidays and on special event days.
