Information and inspiration for residents and visitors
Armstrong’s Engine is a restored and working example of a hydraulic reciprocating engine.
The industrialist and inventor Lord Armstrong designed the engine for his close friend, Thomas Sopwith, mine manager at Allenheads. The engine powered machinery in the mine’s sawmill.
Armstrong would go on to become famous for his military hardware designs, built in his works on the Tyne at Elswick.
The engine has been rebuilt in the Heritage Centre and is a rare working example of the world-famous engineer’s genius. Follow the map to see the engine and learn more.
