Loevestein Castle (Slot Loevestein in Dutch) is a medieval castle built by the knight Dirc Loef van Horne (hence 'Loef's stein') between 1357 and 1397. It was built in a strategic location where the Maas and Waal rivers come together. At first it was a simple square brick building, used to charge toll from trading vessels using the rivers. In the 16th century (around 1575, orders given by William the Silent) it was expanded to a larger fortress surrounded by earthen fortifications with two (later three) stone bastions on the northern side, two moats, an arsenal, and housing for a commander and soldiers.
Loevestein changed hands twice between the Northern Dutch and the Spanish (December 9, 1570 it was taken by the Geuzen, ten days later Spanish again, and from June 25, 1572 Dutch till this day), the warring parties of the day. The castle became a prison for political prisoners in 1619. One famous inmate was the eminent lawyer, poet and politician Hugo de Groot (Hugo Grotius) often presented as the 'father of modern international law', who was serving a controversially imposed life sentence from 1619. In 1621 Hugo de Groot managed to pull off a daring escape in a book chest. The idea for this escape came from his wife Maria van Reigersberg (also living in the castle). He subsequently became the Swedish Ambassador to France for 10 years. Another high profile inmate was the English Vice-Admiral George Ayscue.
Until the Second World War Loevestein Castle was part of the Nieuwe Hollandse Waterlinie, the main Dutch defense line that was based on flooding an area of land south and east of the western provinces. Currently the castle is used as a medieval museum and function centre.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.
