Museo Cartográfico Juan de la Cosa

Museo Cartográfico Juan de la Cosa is a small mapping museum in Potes, the main town of the Liébana region in Cantabria, northern Spain. It occupies the Casa de Cultura, a restored building in the town's historic quarter, and is run by the private Fredo Arias de la Canal foundation. The museum opened in 1998 and has since built up a collection of historical maps tracing geographic discovery from the medieval period through the 18th century.

How do you get there?

Potes sits at the heart of Liébana, ringed by the peaks of the Picos de Europa National Park, and is a common base for travelers exploring inland Cantabria. It's reachable by car or bus from Santander (roughly 1.5 hours) or from Torrelavega. The museum building itself stands in the old part of Potes, a short walk from the main square and the bridges over the Deva river, so a visit fits easily alongside exploring the town on foot.

What's inside the museum?

The core of the collection is a set of original maps from the early modern period, including work by cartographers such as Abraham Ortelius, Jan Janssonius (Blaeu), and Lucas Waghenaer — the mapmakers whose atlases shaped how 16th- and 17th-century Europe pictured the wider world. Alongside them are city views and plans drawn from the "Civitates Orbis Terrarum," the atlas published by Georg Braun and Frans Hogenberg between 1572 and 1618, including historic depictions of Granada, Cádiz, Burgos, and San Sebastián.

Why is the museum named after Juan de la Cosa?

The collection's guiding figure is Juan de la Cosa, a navigator and cartographer born in nearby Santoña. He captained and owned the Santa María, the ship Columbus sailed on his first voyage to the Americas. Around 1500, de la Cosa produced one of the earliest surviving maps to sketch the outline of the newly encountered American continent, and the museum frames its whole collection around that moment in the history of exploration.

Beyond the permanent map collection, the Casa de Cultura hosts rotating photography and painting exhibitions and cultural events, including the annual "Jornadas Hispanistas Lebaniegas" conference organized jointly with a Mexican foundation, along with ceremonies for the international José Vasconcelos award.

When should you visit, and what does it cost?

Admission is free. During the summer season the museum opens daily from 12:00 to 14:00 and again from 17:00 to 21:00 — it's worth confirming current hours before visiting, since a cultural venue of this size can adjust its schedule outside peak season. A visit typically takes 30 to 60 minutes, which makes it easy to pair with other stops in Potes, such as a walk through the old town or a side trip to the nearby Santo Toribio de Liébana monastery.
