The Basilica of St. Martin is the main Catholic church of the city of Bingen am Rhein. The church is located on the bank of the Nahe. It was restored and renovated several times, so it is a fusion of different styles. Around 793 the crypt was built, one of the oldest crypts of Austrasia.
The church is dedicated to St. Martin of Tours, who is depicted above the main entrance and in many frescoes and the altarpiece.
In 1416 the church was enlarged and remodeled in the Lombard Gothic style; in 1505 it was beautified with works of art.
The church has been a minor basilica since 1930.
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.
