Milnes' Orangery is a historic building in the city centre of Wakefield, in West Yorkshire, in England.
[1] In 1795, his daughter, Mary Milnes, the Dowager Viscountess of Galway, inherited the house.
The following year, he donated the garden to the trustees of the neighbouring Westgate Unitarian Chapel.
[2] The last school closed in 1957, and the building served as a hall for the chapel until 1996, when it was purchased by the Public Arts charity, which ran events at the venue.
Part of the central section has large sash windows, added in the mid 19th century.
