Engine House At Sw613310 Polrose Mines

The engine house at Polrose Mines is a disused beam engine house built around 1873. It features granite rubble walls with dressed granite quoins, coursed dressed granite on the bob wall, round-headed brick arches, and some wooden lintels. A round granite rubble chimney is located at the north-east corner, adorned with a moulded brick cornice and a tapered brick shaft that shows traces of a cornice above.

The building has a rectangular single-cell plan with three original floors surrounding the chimney at the north-east corner and a lower bob wall to the south. The north wall includes a large ground floor opening, which served as a boiler doorway, along with a smaller opening above, both of which are round-headed. The gable above has collapsed, and the chimney is positioned to the left with a small flue opening at the bottom. The south wall, known as the bob wall, features a large round-headed opening that served as a plug doorway. The east and west walls each contain two principal window openings that are irregularly spaced, all with round-headed brick arches, except for the lintelled opening on the ground floor of the west wall.

There may be remnants of associated structures in the overgrown land nearby. Aside from the fallen north gable, the masonry of this engine house is largely intact, and it is situated in unspoiled open farmland. This engine house originally housed a 40-inch cylinder pumping engine, which was still operational during reworking in 1880, along with two other engines, until its abandonment in 1884.
