Brill, Boarstall and Muswell Hill
Overlooking the Vale of Aylesbury β from a hilltop village along quiet country lanes and fields. The walk begins at the edge of the attractive village of Brill. This is an area of common land, full of humps and hollows, the marks of old pits from which clay was dug for brick-making and a pottery industry that dates back to the Middle Ages. The village is 613 feet (187 metres) above sea level, and looks out over the Vale of Aylesbury. The most prominent building is the 17th-century Brill Windmill. This is one of the oldest post mills in England. The actual milling machinery is in the weatherboarded "buck" to which the sails are attached. This is balanced on a central post, hence the name post mill β and the whole structure can be rotated to bring the sails into the wind.
