A museum of shipbuilding housed in the vast 18th-century Herrerías building inside Ferrol's naval complex — full-size boats, models and machinery telling the story of how ships are made.
Exponav occupies the Arsenal's former ironworks building (18th century), its vaults resting on 132 stone arches. It's Spain's great shipbuilding museum — one of the most important in Europe: huge models and centuries of vessels built in Ferrol.
