Description
Chestnut Mills is a woollen mill built around 1885, constructed from rubble stone with a slate roof and a stack at the north end. The building is three storeys high and features an eight-window facade facing the river, with 12-pane fixed-light windows. The lower two floors have stone voussoirs, while the top floor is supported by timber lintels. There is a door located in the seventh bay of the ground floor. An additional brick workshop has been added against the eighth bay. The south end of the mill has a large overshot waterwheel marked "Thomas Jones Priory Foundry Carmarthen." The north end includes a basement door, a first-floor door (which is at ground level due to the embanked ground), a 12-pane window above, and two attic windows with nine panes each. The rear elevation is obscured by a parallel range added around the 1930s when the mill was converted for use as a creamery. This extension is made of red brick and features a concrete loading platform.
