The infamous church of gravel as we called it. Nice to look at, and conveniently placed next to great gravel roads and even a single track!

Really beautiful castle in the middle of a semi arid landscape with perfect gravel roads. Surprisingly empty!

Founded and built by Sancho Ramírez of Aragón in Romanesque style in the 11th and 12th centuries, Montearagón Castle was a fortified complex that included military housing, a church and a royal monastery. It is located on a strategic promontory in the Huesca town of Quicena, in the Hoya de Huesca region, Aragon. Although its military function ended with the taking of Huesca and the end of the Spanish-Arab wars, it continued to house the canonical abbey under the name of the Abbey of Jesús de Nazaret de Montearagón. Several Aragonese kings were buried in the castle in addition to its founder, Sancho Ramírez of Aragón.

The church of San Martín de Foces is a linear Gothic style temple from the 14th century. It was ordered to be built by Ximeno de Foces in 1249 as a family pantheon, and later donated to the Order of Saint John of Jerusalem. It is the only vestige of the ancient town of Foces, and was declared a National Monument in 1916. It is highly appreciated for the sarcophagi and the fresco paintings located in the side arms of the temple.

Really take the time to come and discover this site. An atmosphere steeped in history. And an opportunity to get in the shade. A siesta?
