Paris is densely covered by a metro system, the Métro, as well as by a large number of bus lines. This interconnects with a high-speed regional network, the RER, and also the train network: commuter lines, national train lines, and the TGV (or derivatives like Thalys or Eurostar for specific destinations). There are two tangential tramway lines in the suburbs: Line T1 runs from Saint-Denis to Noisy-le-Sec, line T2 runs from La Défense to Issy. A third line along the southern orbital road is currently under construction.
The furious crowd began attacking the palace and were only placated when Louis himself appeared and agreed to return to Paris with his family. The royal family were reduced to virtual prisoners in the Tuileries. They tried to escape on 20 June 1791 but were caught and returned to Paris as captives.
The Louvre was redeveloped and acquired its spectacular glass pyramid, while a futuristic new district was constructed just outside the city limits at La Defense. The Opéra Bastille and Bibliotheque Nationale de France François Mitterrand proved less successful, experiencing big cost overruns and a series of technical problems.
Louis' reign saw major changes to the face of Paris; his mother commissioned the Palais du Luxembourg, while Cardinal Richelieu built the Palais Royal and rebuilt the Sorbonne. He also commissioned a number of major Baroque churches as a statement of the Catholic Counter-Reformation.
The city of Paris also comprises two forests: the Bois de Boulogne on the west and the Bois de Vincennes on the east.
Louis XIII became king at the age of only eight, with political power exercised by his mother Marie de Médicis in the role of regent. Although Louis took over when he reached the age of majority, at 15, the real power was exercised by the brilliant but ruthless Cardinal Richelieu, who greatly expanded royal power.
