The Old Mill

The Old Mill is a building dating from the 18th century, constructed of rubble stone with a slate roof. The roof overhangs at the gables and features verge brackets. A stone chimney stands on the east end. Grey limestone quoins and stone voussoirs frame the openings. The building is two storeys high, with a seven-window range on the front, comprising a four-window factory to the left and a three-window house to the right. Originally, the house windows were 12-pane sash windows, while the factory windows were slightly shorter and broader 12-pane tilting windows. However, both the house and mill now have 20th-century PVCu windows, with the ground floor of the mill having replacement PVCu windows. Stone sills are present throughout. A door has been inserted into the fourth bay of the mill, replacing a window. The house has a 20th-century door and overlight in its original central position. A first-floor sill in the fourth bay of the mill is broader and inscribed 'Vale of Towy Factory 1872'. A 20th-century three-light flat dormer replaces an earlier one.

The rear of the building features a two-window range on each side of a two-storey red-brick addition with cambered-headed openings. This addition has one window above a door and window, mirroring the appearance of the west and east sides. A loft door is present on the north end. The rear of the mill retains two original upper-floor windows, while the rest of the rear windows are 20th-century replacements. The rear of the house also features 20th-century windows and a central door.

A wheel-pit at the west end contains a very large iron water wheel, said to be 7.6 metres (25 feet) in diameter, marked on the rim 'M. Griffin & Bros Vulcan Foundry Galway 1849'. Another wheel-pit, closer to the end wall, apparently housed a second wheel that generated electricity. The end wall has a window on each floor, with 12 panes on the ground floor.

The mill has undergone mostly alterations, although its upper floor remains largely unaltered, consisting of a single room measuring 14 metres by 7.9 metres, which is also open to the upper floor of the brick extension. The house includes a large east-end fireplace lintel, a brick grate, and an enamel oven.
