The Church of Saint Sulpice is a Roman Catholic church in Jumet, a neighborhood Charleroi. It is dedicated to Sulpitius the Pious. The oldest material traces of a religious building on the site date back to the 10th century. Three churches preceding the current construction were identified during excavations carried out in 1967. The current building was built between 1750 and 1753 in a classical style, by an anonymous architect. The brick and limestone church is quite homogeneous. It's composed of six bayed naves flanked by aisles, a three-sided transept and a choir with a polygonal ambulatory with a sacristy in its axis. The chamfered base is in dimension stone on the frontage, in rubble stones and sandstone for the rest. All the angles of the building are toothed and every second stone is bossed. The church has been listed as a Belgian cultural heritage site since 1949.
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.
