The name SOUTHERTON is derived from ‘South of Town’, the town being Fen (Venn) Ottery about half a mile to the north. The hamlet of some 40 souls is clustered around Southerton House, a large Victorian/Edwardian establishment which included a coach house and stables; a dower house; walled garden; water tower and a squash court. The hydraulic ram which fed the tower, a Japanese garden (now derelict) and a number of other dwellings is still in working order. The hamlet is also home to the Southerton Stompers!
