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.

An alternative to the descent on the track. Be careful, it's a challenging climb.

A stream that must be crossed to get to Miraflores. There is a narrow little bridge that we can cross.
