The Archcathedral Basilica of St. Peter and St. Paul in Poznań is one of the oldest churches in Poland and the oldest Polish cathedral, dating from the 10th century. It stands on the island of Ostrów Tumski north-east of the city centre.
The cathedral was originally built in the second half of the 10th century within the fortified settlement of Poznań, which stood on what is now called Ostrów Tumski ('Cathedral Island'). This was one of the main political centres in the early Polish state, and included a ducal palace (excavated by archaeologists since 1999, beneath the Church of the Virgin Mary which stands in front of the cathedral). The palace included a chapel, perhaps built for Dobrawa, Christian wife of Poland's first historical ruler, Mieszko I. Mieszko himself was baptised in 966, possibly at Poznań – this is regarded as a key event in the Christianization of Poland and consolidation of the state. The cathedral was built around this time; it was raised to the status of a cathedral in 968 when the first missionary bishop, Bishop Jordan, came to Poland.
Saint Peter became the patron of the church because, as the first cathedral in the country, it had the right to have the same patron as St. Peter's Basilica in the Vatican. The pre-Romanesque church which was built at that time was about 48 meters in length. Remains of this building are still visible in the basements of today's basilica. The first church survived for about seventy years, until the period of the pagan reaction and the raid of the Bohemian duke Bretislav I (1034–1038). The cathedral was rebuilt in the Romanesque style, remains of which are visible in the southern tower.
In the 14th and 15th centuries, the church was rebuilt in the Gothic style. At that time, a crown of chapels was added. A fire in 1622 did such serious damage that the cathedral needed a complete renovation, which was carried out in the Baroque style. Another major fire broke out in 1772 and the church was rebuilt in the Neo-Classical style. In 1821, Pope Pius VII raised the cathedral to the status of a Metropolitan Archcathedral and added the second patron - Saint Paul. The last of the great fires occurred on 15 February 1945, during the liberation of the city from the Germans. The damage was serious enough that the conservators decided to return to the Gothic style, using as a base medieval relics revealed by the fire. The cathedral was reopened on 29 June 1956. In 1962, Pope John XXIII gave the church the title of minor basilica.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.
