Turnavore Engine House (At Sw71785134)

The Turnavore Engine House is a late 19th-century pumping beam engine house located in St Agnes. It is constructed from killas rubble with granite and brick dressings, and features a brick upper part of the chimney. The roof is made of corrugated asbestos with gable ends. The building has a rectangular plan and a round chimney that clasps the rear left-hand corner.

The engine house stands three storeys tall, with unaltered elevations, although some openings have been blocked. It has round-arched doorways at the front and rear, and pointed-arched principal window openings. The front wall has a central doorway, while the second floor and gable are clad in weatherboarding. The rear wall includes a wide central cylinder doorway within a later lean-to, and large central windows on each floor above. The right-hand wall features a doorway on the left, blocked openings on the first floor, and a large window on the second floor. The left-hand wall has a large window on the right and another large window in the middle of the first floor. The large windows are fitted with old 6-pane casements, and the tympana of their pointed arches are weather-boarded.

The interior of the engine house was not inspected. This building was last reworked in 1941 and is notable for being one of the few engine houses in the county that still has a roof.
