Barony Mill

Barony Mill, tucked away in the scenic landscape of Birsay, is Orkney's last working water mill and a living link to the islands' agricultural past. Built in 1873, the mill is still powered by water and continues the centuries-old tradition of grinding bere, an ancient barley cultivated in the region since Neolithic times. The mill remains largely unchanged since its construction, preserving both its architecture and its traditional milling methods as a rare piece of industrial heritage.

A visit to Barony Mill is a sensory journey into history. The rhythmic turning of gears, the scent of kiln-dried grain, and the sound of the waterwheel in motion all evoke the mill's long-standing role in the community. The mill comes alive in winter, when the burn is at its fullest and the waterwheel powers the entire milling process, just as it has for generations.

One of the most remarkable features of Barony Mill is its overshot waterwheel, which measures about 4.1 metres in diameter and turns at roughly 12 revolutions per minute. To operate at full capacity, the wheel requires an astonishing 500,000 litres of water per hour, drawn from the nearby Boardhouse Loch. This large flow of water drives all the mill's machinery, including the grindstones, elevators, and sieves, making Barony Mill a marvel of traditional engineering.

The mill's story is also one of people and tradition. Generations of local millers, including the Phillips family, have kept the mill running, passing down their expertise and passion. Today, the Birsay Heritage Trust oversees the mill, ensuring its continued operation and offering guided tours in the summer months. Visitors can explore the building, see the historic machinery in action, and discover the unique story of bere barley and its importance to Orkney's heritage.

Barony Mill stands as a testament to Orkney's resilience and ingenuity, offering a rare glimpse into the island's past and the enduring legacy of its last working water mill.
