The Church of Saint-Germain-l'Auxerrois was originally founded in the 7th century, but it has been rebuilt many times over several centuries. It now has construction in Roman, Gothic and Renaissance styles. The most striking exterior feature is the porch, with a rose window and a balustrade above which encircles the whole church, a work of Jean Gaussel (1435–39). Among the treasures preserved inside are a 15th-century wooden statue of Saint Germain, a stone carved statue of Saint-Vincent a stone sculpture of Isabelle of France (saint), a Flemish altarpiece carved out of wood, the famous 'churchwarden's pew' where important people sat, made in 1683 by François, Le Mercier from drawings by Charles Le Brun.
During the Wars of Religion, its bell called 'Marie' sounded on the night of 23 August 1572, marking the beginning of the St. Bartholomew's Day Massacre. Thousands of Huguenots, who visited the city for a royal wedding, were killed by the mob of Paris. A splendid stained glass still remains, in spite of plunderings during the French Revolution. The north tower was added in 1860 and stands opposite the Mairie of the 1st Arrondissement (1859).
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
