Description

This is a detached mine chimney, built around the late 19th century. The lower stage is made of granite rubble, while the upper stage is constructed from brick. The chimney has a round, tapered flue with a round-arched opening at the base and an echinus moulding at the brick collar that separates the two stages. The upper part of the chimney is partly fallen. It is similar in design to the chimneys at Tregembo Mine.
