Green: One of the oldest chalk carvings in the UK is the bronze-age Uffington White Horse. Dating back some 3,000 years it's still very visible on the slopes of White Horse Hill, Uffington. It is one of England's most famous prehistoric monuments & has inspired a number of poems and stories inc. in works by G.K. Chesterton, Rosemary Sutcliff & Terry Pratchett.
The Uffington White Horse is a highly stylized prehistoric hill figure, 374 feet long, formed from deep trenches filled with crushed white chalk. The figure is situated on the upper slopes of White Horse Hill in the English civil parish of Uffington (in the county of Oxfordshire, historically Berkshire). The figure presumably dates to "the later prehistory", i.e. the Iron Age (800 BC–AD 100) or the late Bronze Age (1000–700 BC).
The Uffington White Horse is a highly stylized prehistoric hill figure, 110 m long (374 feet), formed from deep trenches filled with crushed white chalk. Believed to be based on the similarity of the horse's design to comparable figures in Celtic art, and confirmed following a 1990 excavation led by Simon Palmer and David Miles of the Oxford Archaeological Unit, following which deposits of fine silt removed from the horse's 'beak' were scientifically dated to the late Bronze Age
