The first Vannes Cathedral was erected around 1020 in Romanesque style. The tower is only structure left from it and accommodates the four bells of the church. The present Gothic building was erected on the site of the former cathedral. Its construction extends from the 15th to the 19th centuries, or if the length of the existence of the 13th century Romanesque bell tower is included, a total of seven centuries of construction. In this period the nave and the ornate gateway at the northern end of the north transept – whose twelve niches, according to Breton custom, were supposed to accommodate the Apostles – were built high. The northern tower is the main remnant of the former Romanesque building, while the vaults and the choir were built between 1771 and 1774.
The façade was carved in 1857 in a neo-Gothic style. Outside, in front of the central pillar of the large gate, stands a statue of the Dominican monk St. Vincent Ferrer, from Valencia. His activities in the 15th century greatly influenced Christianity in Vannes. The northern façade opens onto the garden of the cloister (ruins from the 16th century) and the Rue des chanoines ('Street of the Canons') through the beautiful portal at the top of the north transept, built in a Flamboyant late Gothic style (1514), and decorated with twelve niches designed to house statues of the twelve apostles. The cross, visible close to the northern façade, dates back to the 15th century and was brought from the cemetery.
During the Middle Ages, the floor of the cathedral had been covered by tombstones. For hygienic reasons, only the tradition of burying the bishops in their episcopal church has been preserved. However, some tombstones have been returned and can be seen today. The cathedral has only retained tombs dating back to the 17th century. Two bishops' tombs can be found in the crypt under the choir.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
