Sherdley Park is a 336 acre park in the district of Sutton in St Helens. Sherdley Park is the largest park in the town. It includes an 18-hole golf course, a formal garden, open woodland, a lake, pets' corner and summer events. It is well known in the local area for hosting the St Helens Festival (originally called the St Helens Show), a large annual three-day event attended by up to 500,000 people.
Originally owned by the family of 19th century coal and copper baron, Michael Hughes, it was purchased by the local authority after the second world war as a place of relaxation for the citizens of Sutton.
