The Church of San Esteban de Aramil is of the Romanesque style, popular between the 10th and 13th centuries, but the church itself cannot be dated more exactly. It was first mentioned in documents from 1240 concerning a donation of goods to the monastery of Valdediós by Alvar Diaz and his wife.
There are two theories concerning its origin; one is that it is the last remaining remnant of a monastery and the other is that it is a nobleman's church, which would have served both as the chapel for the castle and the church for the neighboring town.
The church has the classic features of Romanesque architecture; it has a rectangular nave terminated at the southern end by a semicircular apse. Sculptural ornamentation of the church includes the doors, located on the western side of the church and in the apse. The west door has a semicircular arch with two semiarches and screens that rely on separate columns. These columns are formed by shafts supported on bases that have carved lilies forming the columns' capitals, which are decorated with plant motifs. The southern section is less important in addition to being smaller although it is similar in design to the western door. The decor includes protruding sculptured heads, of Norman origin, showing various imaginary animals. There is a small central window in the apse.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
