There are 17,000 people of working age in Rutland, of which the highest percentage (30. 8%) work in Public Administration, Education and Health, closely followed by 29. 7% in Distribution, Hotels and Restaurants and 16. 7% in Manufacturing industries. Significant employers include Lands' End in Oakham and the Ketton Cement Works. Other employers in Rutland include two Ministry of Defence bases – Kendrew Barracks (formerly RAF Cottesmore) and St George's Barracks (previously RAF North Luffenham), two public schools – Oakham and Uppingham – and one prison, Stocken. The former Ashwell prison closed at the end of March 2011 after a riot and government review but, having been purchased by Rutland County Council, has now been turned into Oakham Enterprise Park. The county used to supply iron ore to Corby steel works but these quarries closed in the 1960s and early 1970s resulting in the famous walk of "Sundew" (the Exton quarries' large walking dragline) from Exton to Corby, which even featured on the children's TV series Blue Peter. Agriculture thrives with much wheat farming on the rich soil. Tourism continues to grow.
