The Plaza de España in Reinosa is, like in so many others, a meeting place and a venue for celebrations. Don't miss visiting it and, if you have time, relaxing on one of its terraces trying some of the local tapas.

Officially, it's the source of the Ebro River, in Fontibre. However, according to what we were told at the tourist office, the waters of the spring pools come underground from the Hijar River, which rises in Alto Campoo. Specifically, in Tresmares, where the Hijar-Ebro begins, flowing into the Mediterranean; the Pisuerga (a tributary of the Duero) flows into the Atlantic; and the Nansa flows into the Cantabrian Sea.

On a hill, and guarding the road that linked the coast with Castilla through the Saja Valley, is the Castillo de San Vicente, in Argüeso, within the municipality of the Brotherhood of Campoo de Suso, in the South from Cantabria (Spain). Built during the 13th, 14th and 15th centuries, it was the emblem and fortress of the dominion of the House of Mendoza in the highlands of Campoo.

Fontibre is a small town in the Brotherhood of Suso, just 5 km from Reinosa. Beautiful town and place, where the source of the Ebro River is traditionally located. In fact, the name Fontibre refers to the source of the Ebro, as it derives from the Latin Fontes Iberis ("sources of the Ebro") and is already cited by Pliny the Elder when he mentioned it. It is located near the Roman city of Julióbriga. It doesn't matter when you visit, or at the time of year, because you will always appreciate and enjoy this little walk through the place.

Beautiful 12th century church and an example of Romanesque-style religious architecture in southern Cantabria. The church is listed as an Asset of Cultural Interest. Inside it has a small interactive museum.

Located between high mountains far from the sea, the fascinating thing about this city is that it dates back to the Middle Ages, with an old town with interesting monuments to visit. The structure that stands out the most is the church of San Sebastián in the old center of the city. Furthermore, in the Town Hall Square you can see a set of ashlar buildings, built in the 16th and 17th centuries. Don't forget to try the city's most typical sweet, calf, which is a puff pastry with caramelized sugar.
