Eskelhem Church was preceded by a wooden church, of which nothing remains. Circa 1200 it was replaced by a stone church. The walls of the nave of the present church are all that remains of this edifice. The church was successively enlarged and rebuilt until it received its present form in the middle of the 14th century.
Internally, the church is decorated with different sets of frescos, dating from the end of the 13th century and the 15th, the latter by the Master of the Passion of Christ. Among the church furnishings, the baptismal font from the 12th century, probably made by Master Byzantios, and the triumphal cross, made around 1250 both deserve mention.
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.
