The Basilica of Saint Severinus is built upon a Christian necropolis dating to the 4th century CE. The epitaph of Flavinus was engraved beneath a representation of a chrism on the lid of a sarcophagus dating to between 365 and 385 CE, testifying to the Christian presence in Bordeaux to Late Antiquity. Today, it is housed in the Museum of Aquitaine in Bordeaux.
At the beginning of the 11th century, the canons of the basilica decided to commence a major reconstruction. It has the shape of a robust Romanesque church in the basilical form. During the course of the 11th through 13th centuries the nave and the choir were built. In the 13th century, the canons ordered the construction of the southern entry which is surmounted by a porch with a belfry built in the Renaissance style. The entrance consists of a large bay flanked by two blind arches and is decorated with fourteen carved statues representing the twelve apostles and two female statues representing the Synagogue and the Church. The church has three tympana: the main one is decorated with scenes from the Resurrection and the Judgement; the left has a representation of the holy women who visited the tomb; and the right depicts the arrival of Saint Severinus according to Saint Amand's dream. The five-sided porch that leads to it was built later.
The 14th and 15th centuries mark the construction of several chapels. One of them was the Chapel of Madonna of the Rose which was dedicated to the Virgin. It contains an altar that was consecrated by Archbishop Pey Berland in 1444. It was designed in the flamboyant Gothic architecture reminiscent of that found in late-15th-century Normandy and England.
Twice in 1566 and 1698, parts of the church's vault structure collapsed causing serious damage. At the beginning of the 18th century, the architect Jean-Baptiste Augier was charged with rebuilding and bracing them with pillars equipped with stone belt courses.
The basilica has benefited from restoration in recent decades. The roofs were redone, as were upper parts of the basilica. The chapels of Madonna of the Rose and Saint John as well as choir were restored. The church is then inscribed as a UNESCO World Heritage Site in 1998 due to it being the head of one of the Ways of Saint James of Compostela.
The church has retained an ornate 15th-century episcopal pulpit that still has its armrests, backrest and dais. This is a very significant item as it is reserved for the new archbishop of Bordeaux who must take an oath on the relics of Saint Severinus before he is nominated.
The choir still houses thirty-two of the forty-seven stalls from the 15th century. These stalls were intended for the chapter. They are decorated with images of saints, prophets and satirical scenes.
The Basilica of Saint Severinus has a number of well-maintained medieval statues. Among them, are the 13th-century Our Lady of Glad Tidings, the 14th-century alabaster Madonna of the Rose and one of Saint Martial.
The ancient crypt houses sepulchres of the Merovingian family.
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.
