St Peter's Abbey in the Black Forest (Schwarzwald) is a former Benedictine monastery. The monastic community was the house monastery and burial place of the Zähringen family. It was originally founded in Weilheim, in or before 1073, but was forced by hostile military action during the Investiture Controversy to move to Hirsau. Duke Berthold II of Zähringen (1078–1111) re-founded it as a family monastery, but decided in about 1090 to move it to the site which is now St. Peter im Schwarzwald.
Here it soon developed as a reformed Benedictine monastery directly answerable to the papacy, as witness for example the privilege of Pope Urban II of 10 March 1095. The Vögte (lords protectors) were initially the Zähringen family but, in the late 13th century, they were succeeded by the Counts of Urach, against whom the monks were eventually obliged to seek the protection of Emperor Charles IV. In 1526 the office passed to the Habsburgs.
By the gift of the Zähringen family and their ministeriales the abbey acquired substantial property, particularly in the 11th and 12th centuries, located in the immediate area, in the Breisgau and in the Baar region, near Weilheim. The abbey, like most other landowners of the time, suffered significant loss of income and tenants after the middle of the 14th century.
The abbey suffered disastrous fires in 1238 and again in 1437. It lost importance in the later mediaeval period, and the monastic reforms of the 15th century had little effect here. Nevertheless, it managed to keep its property intact, even through the troubles of the Reformation. The premises were re-built in Baroque style in the 17th and 18th centuries; the present church with the two onion towers was built in the 1720s. The architect was Peter Thumb, and the opulent Baroque decoration was by Franz Joseph Spiegler (55 frescoes, 1727) and Joseph Anton Feuchtmayer (sculptures), among other artists and craftsmen. Peter Thumb also constructed the library. The abbey was dissolved in the secularisation of 1806.References:
The famous Italian Medici family have given two queens to France: Catherine, the spouse of Henry II, and Marie, widow of Henry IV, who built the current Luxembourg palace. Maria di Medici had never been happy at the Louvre, still semi-medieval, where the fickle king, did not hesitate to receive his mistresses. The death of Henry IV, assassinated in 1610, left the way open for Marie's project. When she became regent, she was able to give special attention to the construction of an imposing modern residence that would be reminiscent of the Palazzo Pitti and the Boboli Gardens in Florence, where she grew up. The development of the 25-hectare park, which was to serve as a jewel-case for the palace, began immediately.
The architect, Salomon de Brosse, began the work in 1615. Only 16 years later was the palace was completed. Palace of Luxembourg affords a transition between the Renaissance and the Classical period.
In 1750, the Director of the King's Buildings installed in the wing the first public art-gallery in France, in which French and foreign canvases of the royal collections are shown. The Count of Provence and future Louis XVIII, who was living in Petit Luxembourg, had this gallery closed in 1780: leaving to emigrate, he fled from the palace in June 1791.
During the French Revolution the palace was first abandoned and then moved as a national prison. After that it was the seat of the French Directory, and in 1799, the home of the Sénat conservateur and the first residence of Napoleon Bonaparte, as First Consul of the French Republic. The old apartments of Maria di Medici were altered. The floor, which the 80 senators only occupied in 1804, was built in the middle of the present Conference Hall.
Beginning in 1835 the architect Alphonse de Gisors added a new garden wing parallel to the old corps de logis, replicating the look of the original 17th-century facade so precisely that it is difficult to distinguish at first glance the old from the new. The new senate chamber was located in what would have been the courtyard area in-between.
The new wing included a library (bibliothèque) with a cycle of paintings (1845–1847) by Eugène Delacroix. In the 1850s, at the request of Emperor Napoleon III, Gisors created the highly decorated Salle des Conférences, which influenced the nature of subsequent official interiors of the Second Empire, including those of the Palais Garnier.
During the German occupation of Paris (1940–1944), Hermann Göring took over the palace as the headquarters of the Luftwaffe in France, taking for himself a sumptuous suite of rooms to accommodate his visits to the French capital. Since 1958 the Luxembourg palace has been the seat of the French Senate of the Fifth Republic.
