Dunham Massey Hall

Dunham Massey Hall, usually known simply as Dunham Massey, is an English country house in the parish of Dunham Massey in the district of Trafford, near Altrincham, Greater Manchester. During World War I it was temporarily used as the Stamford Military Hospital.

It was designated a Grade I listed building on 5 March 1959. It has been owned by the National Trust since the death of Roger Grey, 10th and last Earl of Stamford in 1976.

Dunham Massey was re-built in the early 18th century by George Booth, 2nd Earl of Warrington. He had inherited an older mansion from his father, which was in a terrible state of repair.

There were significant alterations, especially internally, at the start of the 20th century. It has historic formal gardens and a deer park. The park and gardens are listed Grade II* on the Register of Historic Parks and Gardens.
