The Byzantine church of the Holy Apostles is located at the start of Olympou Street, near the city's western medieval walls.
As evidenced by remnants of a column to the south of the church and a cistern to its northwest, it originally formed part of a larger complex. Consequently, it appears that the church was originally built as the katholikon of a monastery.
The date of its construction is not entirely clear: the founder's inscription above the entrance, the monograms in the capitals and other inscriptions refer to Nephon I, Patriarch of Constantinople in 1310–1314, as the ktetor. Another inscription on the eastern wall commemorates the same patriarch and his pupil, the hegumenos Paul, as first and second ktetores respectively. Recent analysis using carbon-14 however points to a later date for the entire structure, ca. 1329. A depiction of the hegumenos Paul kneeling before Mary, as well as a series of Marian scenes lead to the conclusion that the church was dedicated to Mary, perhaps to be identified with the Monastery of Theotokos Gorgoepikoos.
The building belongs to the type of the composite, five-domed cross-in-square churches, with four supporting columns. It also features a narthex with a U-shaped peristoon (an ambulatory with galleries), with small domes at each corner. There are also two small side-chapels to the east. The exterior walls feature rich decoration with a variety of brick-work patterns.
The interior gives a very vertical impression, as the ratio of height to width of the church's central bay is 5 to 1. The interior decoration consists of rich mosaics on the upper levels, inspired by Constantinopolitan models. These are particularly important as some of the last examples of Byzantine mosaics (and the last of its kind in Thessaloniki itself). Frescoes complete the decoration on the lower levels of the main church, but also on the narthex and one of the chapels. These too show influence from Constantinople, and were possibly executed by a workshop from the imperial capital, perhaps the same which decorated the Chora Church. They were probably carried out under the patronage of the hegumenos Paul, after 1314 or in the period 1328–1334.
With the conquest of the city by the Ottoman Turks, in ca. 1520–1530 the church was converted into a mosque with the name Soğuksu Camii ('Mosque of the Cold Water'). As was their usual practice, the Ottomans covered the mosaics and frescoes with plaster, after they removed the gold tesserae. The church's modern name, 'Holy Apostles', was not attributed to the building until the 19th century.
Restoration and the gradual revealing of the frescoes began in 1926. After the 1978 earthquake, the building was strengthened, and in 2002, the mosaics were cleaned up.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.
