Banstead Downs is a Site of Special Scientific Interest in Surrey, England (bordering Greater London). It covers 430 acres (1.7 km2). To the west is the A217 and to east is the B2218. The town to the north is Sutton; whilst Banstead lies to the south. It lies at about 125 m above sea level and is bisected by a railway line.
The Downs is one of four green areas in the area referred to as Banstead Commons. The other areas are Burgh Heath (87 acres), Banstead Heath (760 acres) and Park Downs (74 acres). These areas were the focus of a long legal battle in the 19th century.
Banstead Downs is home to the rare Small Blue butterfly.[1]
The four tumuli (burial mounds) that can be seen on the Downs have been identified as dating from Saxon times and are known as the Gally Hills because they are the site of a 15th century gallows.
Much of the Downs is used as a golf course.
