Rockliffe Park near Hurworth, County Durham, is Middlesbrough Football Club's training facility and sports complex.
[1] The grounds and hall were then sold off to Lord Southampton and used as a command headquarters during World War II.
Following extensive research including visiting the academies of clubs like AFC Ajax, Middlesbrough finally developed Rockliffe Park training complex.
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.
Indeed, England trained at the complex prior to their Euro 2004 qualifying match at the Riverside Stadium against Slovakia in 2003.
