Cut into the side of Salisbury Plain, the white horse at Westbury may be one of the later ones in Britain - it's first mentioned in 18th Century records, and has a more naturalistic shape than prehistoric figures such as that at Uffington. It's pretty impressive, and hard to miss as you drive along.
We parked up at the top of the hill and walked along to see the horse up close. It was a blustery day (perfect for the gliders and paragliders circling overhead), and the shape is cut into a very steep bank, so we stayed near the top. There were several anchors set in to the ground, alongside the path, where maintenance workers could rope up when they come to work on keeping the horse gleaming bright white. The natural chalk of the ground provided the original white colour, but I'm not sure if it's currently maintained solely by cutting down to more white chalk, or if they now paint it instead.
