The Diocese of La Rochelle was created in 1648 but the first stone of the new cathedral was not laid until 1742, by which time the architect who drew up the plans, Jacques Gabriel, was dead; the work was supervised, from a distance, by his son Ange-Jacques Gabriel. Although still not complete, it was consecrated anyway in 1784. The structure is a rather bare Neo-Classical one. The cupola has paintings by William Bouguereau, a native of the city.
Attached to the chevet of the present cathedral is the late medieval Gothic bell tower of the Church of St. Barthélémy (Saint Bartholomew), first constructed in 1152 by monks from the Ile d'Aix, the rest of which was destroyed by the Huguenots in 1568. The tower, on one of the highest points of La Rochelle, was used as a gun tower against the besieging army of Louis XIII in 1627.
The displaced parishioners were able in 1628 to take over as their church the grand temple, a former Protestant church adjacent to the site of the medieval St. Barthélémy, only to find in 1648, on the creation of the Diocese of La Rochelle, that the new chapter wished to use it as the cathedral. The parishioners therefore built a new church of St. Barthélémy nearby, which was completed in 1678. The older church however burnt down in 1687 and the chapter moved into the new church, which they and the parish were obliged to share until the consecration of the new cathedral in 1784. The church was entirely destroyed during the French Revolution and the site re-developed with houses, which were demolished later in the 19th century when it was possible to finish the cathedral.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
