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.

The San Andrés Bridge is in Somahoz (Los Corrales de Buelna) over the Besaya River, which gives access to the San Andrés neighbourhood. It is divided into a narrow lane for vehicles and a pedestrian crossing, and from it we see a railway bridge that we have to go under to enter the neighbourhood. And that railway bridge (or overpass) that we crossed is part of the historic "Ferro-carril de Isabel II" (Isabel II Railway) that began to be built in the mid-19th century with the project of joining the towns of Alar del Rey with Santander and whose section from Bárcena de Pie de Concha to the Cantabrian capital must have been finished in 1858.

The Casa Palacio that the Ceballos had in Barros is today owned by Mr. Herrero and Mr. Martínez de Azcoitia. It is a beautiful mountain architectural complex with a portal between cylindrical cubes, a typical mansion and a chapel. It was restored a few years ago by the current owners who have managed to give its interior a stately and period atmosphere. It dates back to the beginning of the 18th century.
