The Conciergerie is a former prison and part of the former royal palace, the Palais de la Cité, which consisted of the Conciergerie, Palais de Justice and the Sainte-Chapelle. Hundreds of prisoners during the French Revolution were taken from the Conciergerie to be executed on the guillotine at a number of locations around Paris.
The west part of the island was originally the site of a Merovingian palace, and was initially known as the Palais de la Cité. From the 10th to the 14th centuries it was the seat of the medieval Kings of France. Under Louis IX (Saint Louis) (1214–1270) and Philip IV (Philip the Fair) (1284–1314) the Merovingian palace was extended and more heavily fortified. Louis IX added the Sainte-Chapelle and associated galleries, while Philippe IV created the towered facade on the river side and a large hall. Both are excellent examples of French religious and secular architecture of the period.
The early Valois kings continued to improve the palace in the 14th century, but Charles V abandoned the palace in 1358, moving across the river to the Louvre. The palace continued to serve an administrative function, and still included the chancellery and French Parliament. In the king's absence, he appointed a concierge to hold command of the palace. This was a very high ranking office, and could be considered the housekeeper for the king. In 1391 part of the building was converted for use as a prison, and took its name from the ruling office. Its prisoners were a mixture of common criminals and political prisoners.
Three towers survive from the medieval Conciergerie: the Caesar Tower, named in honor of the Roman Emperors; the Silver Tower, so named for its (alleged) use as the store for the royal treasure; and the Bonbec ('good beak') Tower, which obtained its name from the torture chamber that it housed, in which victims were encouraged to 'sing'. The building was extended under later kings with France's first public clock being installed around 1370. The current clock dates from 1535. The concierge or keeper of the royal palace, gave the place its eventual name.
Despite lasting only ten months, the Reign of Terror (September 1793-July 1794) had a profound impact on France. More than 40,000 people died from execution and imprisonment, and France would not be a republic again for nearly half a century.
After the Restoration of the Bourbons in the 19th century, the Conciergerie continued to be used as a prison for high-value prisoners, most notably the future Napoleon III. Marie Antoinette's cell was converted into a chapel dedicated to her memory. The Conciergerie and Palais de Justice underwent major rebuilding in the mid-19th century, totally altering their external appearance. While the building looks like a brooding medieval fortress, this appearance actually only dates from about 1858.
The Conciergerie was decommissioned in 1914 and was opened to the public as a national historical monument. It is today a popular tourist attraction, although only a relatively small part of the building is open to public access; much of it is still used for the Paris law courts.References:
The Naveta d"Es Tudons is the most remarkable megalithic chamber tomb in the Balearic island of Menorca.
In Menorca and Majorca there are several dozen habitational and funerary naveta complexes, some of which similarly comprise two storeys. Navetas are chronologically pre-Talaiotic constructions.
The Naveta d"Es Tudons served as collective ossuary between 1200 and 750 BC. The lower chamber was for stashing the disarticulated bones of the dead after the flesh had been removed while the upper chamber was probably used for the drying of recently placed corpses. Radiocarbon dating of the bones found in the different funerary navetas in Menorca indicate a usage period between about 1130-820 BC, but the navetas like the Naveta d"Es Tudons are probably older.
The shape of the Naveta d"Es Tudons is that of a boat upside down, with the stern as its trapezoidal façade and the bow as its rounded apse. Its groundplan is an elongated semicircle. Externally, the edifice is 14.5 m long by 6.5 m wide and 4.55 m high but it would originally have been 6 m high.
The front, side walls and apse of the edifice consist of successive horizontal corbelled courses of huge rectangular or square limestone blocks dressed with a hammer and fitted together without mortar, with an all-round foundation course of blocks of even greater size laid on edge.
