7/266 Trevarno Mill (formerly listed as
- Trevanno Mill)
17.1.80
II
Watermill. Circa early C19, extended circa mid C19 and partly remodelled-circa late
C19, or early C20. Shale rubble with dressed granite quoins, jambstones, sills and
lintels, slate sills to the original part. Hipped asbestos slate roof with the stump
of a brick lateral chimney over the middle of the front wall.
Plan: originally a square mill building possibly with a pyramidal roof, 2 bays wide
with entrance to the middle of the front, built into the bank, left, with loading
doorway to the first floor (level with the bank) and a large overshot wheel at the
rear which operated 3 pairs of millstones. In circa the mid C19, a granary or meal
store, as deep and nearly as wide as the original building, was added to the right-
hand side with a large doorway in the middle of the right hand end wall and 2 first
floor loading doorways. This granary was later refloored to provide 3 floors within
the original space.
2 storeys. Overall 4 window south front comprising the symmetrical 2 window front of
the original mill with central doorway, left, and a 2 window front granary addition,
right, with doorway on its left. Over the doorway of the original mill is inscribed:
MANOR MILL R.PATTEN.
At the rear of the original mill are 2 first floor window opening and a virtually
complete C19 waterwheel with wooden spokes and iron rims. The rear of the granary is
a mirror image of the front except that the original ground floor-window opening has
been converted to a doorway.
Interior has old floors (later roof structure) and hursts bearing complete C19
machinery including 3 pairs of millstones, one of them complete with its wooden
housing and 1 with the top stone detached.
It is interesting to compare the development of this mill with that of other mills
included in this list.
