 The Andrews and Dury maps of Wiltshire in 1773 and 1810 show a racing circuit called "Tylshead Race" a mile south of the house, although this was probably built as a training circuit rather than for use in competitive races.The estate was bought by the War Office in two lots, in 1911 and 1933, in order to extend the Salisbury Plain Training Area.During World War II the house and grounds were used as an army base.
