Come and visit the oldest working steam engines in the world still performing the job they were built to do! There are two beam engines, one of which is an original 200-year-old Boulton & Watt. Both are fed by a hand-stoked, coal-fired Lancashire boiler. These are magnificent pieces of industrial archaeology appealing both to families and steam enthusiasts. The engine house is set in unspoiled Wiltshire countryside close to the old market town of Marlborough.
