Manzanares el Real Castle, also known as Mendoza Castle: Built in 1475 by order of Diego Hurtado de Mendoza, 1st Duke of the Infantado, on the site of a former Romanesque-Mudéjar church. Its architecture is Isabelline Gothic, with a square floor plan, cylindrical towers, and an octagonal keep. It served as the palatial residence of the powerful Mendoza family, who even established a literary court there. Declared a Historic-Artistic Monument in 1949. Today it houses a Medieval Interpretation Center, with exhibits of tapestries, armor, furniture, and audiovisual presentations about life in the Middle Ages.

Many Spanish churches and chapels are dedicated to the Virgin Mary. This one in Bustarviejo bears the inscription "Purísima Concepción," meaning it is dedicated to the Immaculate Conception, a special Marian feast. This term, which may sound somewhat theoretical and difficult to grasp today, expresses the idea that the Virgin Mary was, from the very beginning, freed by God's grace from the burden of original sin—which every human being otherwise carries. This enabled her to freely answer "yes" when the Archangel later announced to her in Nazareth that she would give birth to the Son of God. In 1854, Pope Pius IX declared this article of faith a dogma. The feast day commemorating this occasion—and also the patronal feast of this church—which in Catholic liturgy is officially called the "Solemnity of the Immaculate Conception of the Blessed Virgin Mary," is celebrated annually on December 8th.

A beautiful bridge leads to the Finca de los Batanes, where the hostel is located. Opposite is the El Paular Monastery. From this bridge, there's a path that leads to the village of Rascafría, where I could see people walking and exercising.

It is a good area for a quiet route without rushing... except for some sections with a lot of water where you have to walk.
