Museum of the Royal Artillery Factory

The Museum of the Royal Artillery Factory is a small museum in the village of La Cavada, part of the municipality of Riotuerto in Cantabria, dedicated to the history of the historic royal cannon foundry that once operated there.

The museum occupies a former schoolhouse in La Cavada, now owned by the Riotuerto town council. It is a modest but substantive stop for anyone interested in Spain's industrial and naval history — less famous than the region's headline attractions, but a worthwhile detour if you're already exploring inland Cantabria.

What was the Royal Artillery Factory?

The Royal Artillery Factory of La Cavada operated continuously from 1622 to 1835, making it Spain's first large-scale iron and armaments industry. Drawing on local iron ore deposits and the water power of nearby rivers, the foundry cast naval cannons and ammunition supplied to the Spanish Navy. Output from La Cavada played a real role in maintaining Spain's naval power during the colonial era, arming the galleons that defended the Empire's trade routes across the Atlantic.

What will you see inside?

The exhibition focuses on the technology behind naval artillery production as practiced at the historic foundries. Among the pieces on display are items manufactured on site, including an anchor from an 18th-century frigate and a 48-pound cannon cast in a single piece — a technically demanding feat of period craftsmanship. The museum also hosts periodic themed exhibitions and talks connected to the region's industrial and armaments history.

How do you get there?

La Cavada sits within the municipality of Riotuerto, inland from the Cantabrian coast and a manageable drive from Santander. A car is the practical choice — public transport in this part of Cantabria is limited, so having your own or a rented vehicle makes visiting far easier. It's worth pairing the museum with a walk through the surrounding valley, since remnants of the old ironworks — furnaces, water channels, dams — are scattered across the area.

When should you visit?

The museum runs as a small local cultural institution, so it's worth checking current opening hours before setting out, since they can be limited outside the summer season. Summer tends to bring more cultural programming to the area, making it easier to catch an additional talk or temporary exhibition. Outside peak season, visits are often best arranged in advance with the Riotuerto town council.
