The original blueprints of the Britannia Mine Concentrator provide a fascinating look at the scale, engineering and industrial design of this historic building.
After an earlier mill was destroyed by fire, the new Concentrator was designed by the American engineering firm Bradley, Bruff and Labarthe. Built directly into the mountainside, the structure incorporated materials and construction methods intended to make the new Mill far more resistant to fire.
Designed for a Purpose
One of the most remarkable features of the Concentrator is the close relationship between its architecture and its function. The building was designed around the movement and processing of ore, with machinery, floors and industrial spaces arranged to create an efficient production system.
Its position on the steep mountainside also played an important role in the overall design of the facility.
Exploring the Original Plans
Historic blueprints reveal details that are difficult to appreciate from exterior photographs alone. They document the arrangement of floors, structural elements, machinery and other components that made up the enormous Concentrator.
The plans also demonstrate how industrial engineering could combine practical efficiency with distinctive architecture.
Today, these surviving blueprints are an important historical record, helping us understand how one of Britannia Mine’s most recognizable structures was designed and built.
