Nice Cathedral was built between 1650 and 1699, the year of its consecration. It is dedicated to the Assumption of the Virgin Mary and Saint Reparata.
On the site, the first cathedral was consecrated in 1049. In 1060, relics belonging to St. Reparate (For whom the current cathedral is named) arrived in the city of Nice. By the year 1075 there was construction of a chapel dedicated to St. Reparate. During the later half of the twelfth century, the chapel became the priory of the abbey of Saint-Pons.
The next church on the site was built in the early 13th century on land belonging to the Abbey of St. Pons and became a parish church in 1246.
During the first half of the 16th century a series of acts gradually effected the transfer of the seat of the bishops of Nice from Cimiez Cathedral on the hill of the castle overlooking the city to the church of Saint Reparata which in 1590, after an official ceremony presided over by the then bishop, Luigi Pallavicini, and in the presence of Charles Emmanuel I, Duke of Savoy, was recognised as a chiesa-cattedrale.
However, in 1649, judging the building too small, bishop Didier Palletis commissioned the architect Jean-André Guibert to produce a structure more in keeping with the importance of the city. 1650 to 1685, The construction of a new cathedral (The current main building) occurs during this time. In 1699 the new cathedral is officially consecrated but the construction is an ongoing process.
From 1731 to 1759 the now widely recognized bell tower is built. 1900 marked the most recent addition to the cathedral with the construction of new side chapels which replaced the former heavy baroque ornamentation. The cathedral was declared a minor basilica on 27 May 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.
