The Marlborough White Horse, also called the Preshute White Horse, is a hill figure on Granham Hill, a fairly shallow slope of the downland above the village of Preshute, near Marlborough in the county of Wiltshire, England. Dating from 1804, it is one of several such white horses to be seen around Great Britain, and one of nine in Wiltshire.
Many distant views of the horse are obstructed by trees, but it can be seen from parts of the town of Marlborough. One good view is from a footpath running from Preshute House to the A345 road. Its location is some 500 metres south of the Marlborough College, within 100 metres of the Southeast corner of the sportsgrounds.
The smallest such horse in Wiltshire, the Marlborough horse was cut in 1804 by boys at Mr Greasley's Academy, also called the High Street Academy, a school in the Marlborough High Street which occupied the building now The Ivy House Hotel. This was not the present-day Marlborough College, which is only a short distance away. The horse was designed and marked out on the hill by a boy called William Canning, whose family owned the Manor House at Ogbourne St George. From then onwards, it was "scoured", or cleaned up, every year, this becoming a tradition at the school marked by revelry.
Greasley died about 1830, and the school was closed, leading to the horse being neglected for some years, but by 1860 it was back in good condition and can be seen in a photograph taken that year at a cricket match. In 1873 a Captain Reed, an old boy of Greasley's Academy who had taken part in the horse's creation, saw to a new scouring.
The horse is 62 feet long by 47 high, and it has got thinner since the early twentieth century. It was restored again in September 2001, when it was re-chalked with pure chalk mixed with water and applied with a stiff brush, but by the late summer of 2002 it already had grass growing on much of its surface.
A verse of the Marlborough College school song refers to the horse:
And when to Marlborough old and worn we shall creep back like ghosts,
And see youngsters yet unborn run in between the posts,
Ah, then we'll cry, thank God, my lads, the Kennett's running still,
And see, the old White Horse still pads up there on Granham Hill.
