Brill Windmill: A Timeless Post Mill on Buckinghamshire’s Hilltop

Enduring Legacy of a 17th-Century Post Mill

Brill Windmill is a rare surviving example of a post mill, a type of windmill where the entire wooden body, known as the buck, rotates around a central post to face the wind. Dendrochronological studies date the mill’s timber to winter 1685/86, placing its construction firmly in the late 17th century. This makes it one of the oldest post mills in Britain still standing. Originally built with heavy timbers sourced from the nearby Bernwood Forest, the mill has undergone several phases of repair and rebuilding over the centuries, including major works around 1725, 1757, and the mid-19th century. The brick roundhouse that encases the post was first added in 1865, removed in the 1930s, and reconstructed in 1950 using bricks salvaged from local kilns.

A Hub of Village Life and Milling Heritage

For centuries, Brill Windmill was central to local agriculture, grinding wheat and barley into flour and feed. It operated commercially until 1924, with only six millers recorded over its long working life, each serving on average four decades. The mill’s mechanism includes two pairs of millstones—French burr stones for wheat and Derbyshire grit stones for barley—powered by the sails that once caught the hilltop winds. Though the sails no longer turn automatically, they are manually rotated during special events to preserve the mill’s working heritage. The mill was saved from demolition in 1929 by Sir Henry Aubrey-Fletcher and has since been maintained by trustees and local volunteers.

Architectural and Mechanical Features of Note

The mill’s wooden buck houses the complex internal machinery: hand-crafted wooden gears, shafts, cogs, and pulleys that converted wind power into milling action. The brick roundhouse below protects the structural post and provides storage space. Visitors can explore the interior to see the massive beams, grinding stones, and drive shafts, accompanied by informative displays that explain the mill’s operation. The sails, measuring approximately nine meters in length, are a striking visual feature against the Buckinghamshire skyline, symbolizing rural industry and craftsmanship.

Preservation Efforts and Public Engagement

Brill Windmill is owned by Brill Parish Council and managed by The Brill Society, a registered charity dedicated to its upkeep and public accessibility. The mill underwent significant restoration in 2009 and more recently in 2023, ensuring structural soundness and preserving its historic character. It is open to visitors every Sunday from Easter through September, with an entrance fee supporting ongoing maintenance. Volunteers provide guided tours, sharing stories of the mill’s past and demonstrating its mechanisms. The monthly turning of the sails is a highlight event, combining spectacle with essential preservation work.

The Windmill’s Place in Brill’s Rich Historical Landscape

Perched on the high ground of Brill Common, the windmill overlooks a village steeped in history—from its Anglo-Saxon royal manor origins to its role in the English Civil War. Nearby historical sites, such as the remains of a royal hunting lodge and ancient earthworks, complement the mill’s narrative. The windmill stands not only as an industrial relic but as a symbol of Brill’s enduring connection to its landscape and community traditions.

Visitor Experience and Scenic Surroundings

Visitors to Brill Windmill enjoy panoramic views across Buckinghamshire’s rolling hills and countryside. The site offers a tranquil setting for photography, cultural exploration, and a glimpse into pre-industrial rural life. The mill’s elevated position makes it a landmark visible for miles, while the surrounding common invites leisurely walks.
