What remains of the shipbuilding industry

The shipyards, foundries and engine works have largely disappeared, but the Denny Experimental Tank survives as part of the Scottish Maritime Museum. It is one surviving part of the industrial history documented in the council’s account. Outside the tank stands a marine engine built by Robert Napier for the steamship Leven. The ship was built in Dumbarton in 1824. The tank and engine provide specific examples alongside the history of the larger firms and their yards.
