Stembridge Tower Mill
Stembridge Tower Mill at High Ham is the last surviving thatched windmill in England, a distinction that makes it one of the most unusual and characterful historic structures in the entire country. Owned and preserved by the National Trust, the mill stands as a remarkable testament to rural Somerset's agricultural heritage and to the ingenuity of pre-industrial milling technology. It is a Grade I listed building, reflecting its exceptional national importance, and draws visitors who come specifically to see this singular combination of a working tower mill capped not with the usual wooden or metal covering but with a traditional golden thatch, a sight found nowhere else in England.
The mill was built around 1822, replacing an earlier post mill on or near the same site. It is constructed of the warm local blue lias stone and rises four storeys, its tapering circular tower topped by that famous thatched cap which rotates to face the sails into the wind. The mill remained in commercial use grinding corn until around 1910, operated across its lifetime by members of local farming families. After working life ended it gradually fell into disrepair until the National Trust acquired it in 1969 and undertook careful restoration to preserve it in working order. The sails, the internal machinery, the millstones and much of the original wooden gearing survive and are maintained so that the mill can still turn under the right conditions, keeping alive a tradition of milling stretching back centuries on this hilltop.
Standing beside the mill, the first thing one notices is the extraordinary cap — the thatch is thick and neatly finished, pale gold when dry, sitting atop the grey stone tower with an almost surreal domesticity, as though a cottage roof has been placed on an industrial building. The four double-shuttered patent sails spread out against the Somerset sky in a classic silhouette. When wind conditions are right and the sails are set turning, the creak and rumble of the wooden machinery inside carries clearly on the air, a sound that has not substantially changed in two hundred years. Inside the tower, the floors are connected by steep ladders and the smell of old wood, dust and stone is pervasive. The millstones, the great wooden brake wheel and the iron wind shaft are all visible and authentically in place.
The position of the mill atop the low hill at High Ham rewards the visitor as much as the structure itself. High Ham sits on a prominent ridge above the Somerset Levels, and from the mill and its surroundings the views extend widely across that extraordinary flat landscape — the peat moors, the rhynes and willow-lined drains, the distant Glastonbury Tor rising with improbable sharpness from the plain, the Mendip Hills to the north and the Quantocks to the west. This elevated location was, of course, precisely why the mill was built here: reliable wind is far easier to catch on a ridge above the sheltered moors below. The village of High Ham itself is a quiet and attractive Somerset settlement, with a fine medieval parish church of St Andrew within easy walking distance.
Visiting the mill is a gentle and rewarding experience. The National Trust opens it on selected days during the summer season, typically on Sunday and Bank Holiday afternoons from April or May through to September or October, though opening days vary year to year and it is worth checking the National Trust website before visiting. On open days, knowledgeable volunteer guides are usually present to explain the machinery and history. Access is on foot across a short path and the site is compact. Parking is limited and the lanes around High Ham are narrow, so care is needed when driving. The mill is not far from Langport, Somerton and Street, and could comfortably be combined with a visit to Glastonbury or the nearby Muchelney Abbey.
One of the more touching details of the mill's story is how close it came to being lost entirely before the National Trust stepped in. By the mid-twentieth century the thatch was deteriorating, the machinery was seized and the future of the building was uncertain. Its survival is owed in large part to local interest and the National Trust's commitment to maintaining not just the shell but the working innards of the mill, ensuring that future generations can see and hear the machinery in motion. The combination of that impossible thatch, the wide Somerset sky, the view across the Levels to Glastonbury Tor, and the deep quiet of the hilltop village makes Stembridge one of those places that leaves a disproportionately strong impression for its modest size.
