The Romanesque church of San Saturnino was probably built between 1180-1200 over the primitive church. The Romanesque church was suffered by several attacks during the course of conflicts with neighboring towns in the 13th century. The current Gothic appearance dates from the 13th century.
Located on Calle San Saturnino, the portico offers a set of Gothic-style sculpture made between the late 13th and early 14th centuries. It is preceded by a 16th century atrium made up of several vaults with pointed arches, being decorated with beautiful Gothic carvings.
The two towers are from medieval times, reaching a height of 55 m. They are part of the characteristic layout of the Pamplona skyline.
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.
