Early years (1863-1996)

In 1863, Arthur Backhouse (a member of the Quaker banking family of Darlington) built Rockliffe Hall, then known as Pilmore Hall.^[1] The grounds and hall were then sold off to Lord Southampton and used as a command headquarters during World War II. The estate was then split amongst the family and then sold to the Brothers Hospitallers of St. John of God in 1948.^[2] The brothers built St Cuthbert's Hospital, and remained there until the Order moved to nearby Scorton in 1991.^[3]

Ownership by Middlesbrough F.C. (1997-date)

Following a period in which the area had been unused, Middlesbrough purchased Rockliffe Park in 1997. Following extensive research including visiting the academies of clubs like AFC Ajax, Middlesbrough finally developed Rockliffe Park training complex. It was constructed by Riverside Stadium builders Taylor Woodrow and cost £7 million.^[4] The complex was officially opened on 29 October 1998 by British Prime Minister Tony Blair.

Following heavy rain in early September 2008, part of the Rockcliffe training complex flooded after the River Tees broke its banks, leaving an area the size of four football pitches under four feet of water.
Billingham Synthonia and their reserve team also use the training facilities at Rockliffe.^{[5][needs update]}
