During the civil war, Almería was the Republicans’ last holdout province in Andalucía, and was repeatedly and mercilessly bombed. The attacks prompted a group of engineers to design and build the Refugios, a 4.5km-long network of concrete shelters under the city. Visits – by 1¼-hour guided tour, available in English as well as Spanish – take you through 1km of the tunnels including the re-created operating theatre and storerooms. Advance reservations essential.
