León - Basílica de San Isidoro

León was founded in 68 AD for a Roman legion from which they were supposed to pacify the rebellious mountain dwellers of Asturias and Cantabria. The name of the settlement that was then developed is based on a refined form of the Latin word "legio".

After the end of the Roman Empire, the city was conquered by the Visigoths and in 712 by the Moors. In 856, after the reconquest under King Ordoño I of Asturias, the city was repopulated. Ordoño II made León the capital of his kingdom of León in 914. Sacked by Almanzor in about 987, the city was reconstructed and repopulated by Alfonso V,

León was an important stop on the Way of St. James to Santiago de Compostela. Traders and artisans settled in the suburbs and had a strong influence on the development of the city from the 13th century onwards. In the early Middle Ages, the city became prosperous through the cattle trade. However, from the 16th century until the 19th century, the economy and population declined.
The Basílica de San Isidoro de León is located on the site of an ancient temple to the Roman god Mercury. In the 10th century, the kings of León established a community of Benedictine sisters on the site.

Following the conquest of the area by Al-Mansur (938–1002), the church was destroyed and the area devastated. León was repopulated and a new church and monastery established in the 11th century by Alfonso V of León.

In 1063 the basilica was dedicated to Saint Isidore of Seville. Isidore was the archbishop of Seville and the most celebrated academic of Visigothic Spain in the period preceding the Arab invasions. With the agreement of the Muslim ruler of Seville, Isidore's relics were brought to Leon where they could be interred on Christian soil.

The church benefited from its position on the pilgrimage route to Santiago de Compostella. Sculptors, stonemasons, and artists from across Europe gathered to work on the monastery.

Puerta del Perdón
It is called "Puerta del Perdón" because it was the door through which the pilgrims entered, to obtain the corresponding indulgences and forgiveness of sins in this church.

The tympanum is divided into three parts that show three different reliefs with three scenes: Ascension, Descent and Empty Sepulcher that the three Marys contemplate. The lintel rests on lion and dog heads.
