Carr Bridge Bricks
Cheshire, England, 2004

Carr Bridge, near Culcheth, was built by the great engineer George Stephenson, as part of the world's first passenger railway. The bridge allows a farm track to pass through the high embankment which he constructed to keep the railway as level as possible.

The track under the railway runs almost due North, so the inner walls of the bridge hardly ever receive direct sunlight. In almost two centuries of dull and damp conditions, the bricks have been colonised by a variety of micro-organisms.
