Overview
Dumbarton is a compact stopover on the north shore of the Clyde, best known for its dramatic castle perched on a 240-ft volcanic basalt crag. The Denny Ship Model Experiment Tank preserves a Victorian-era 100-m testing facility where engineers refined hull designs before full-scale construction.
