THE 'Red City' is a fusion of two neighbouring cities, which grew up separately over the centuries, after the sack of Augustoritum during the Barbarian invasions, and were not united until the French Revolution.

One is the ancient cathedral quarter, rising up above the river banks. The Gothic cathedral of St Etienne still dominates the scene, despite having lost its spire, struck by lightning in the XVIc. It is surrounded by the gardens of the bishop's palace, which has vast subterranean passages. The Musee de l'Evéche inside the palace displays fine enamels dating back to the Xllc, as well as Egyptology, a lapidary collection and paintings by Auguste Renoir, who was born at Limoges in 1841. Excellent exhibitions are staged here, such as the International Biennial of Contemporary Enamel.

Nearby is the Musee de la Resistance, commemorating the exploits of the maquis, which was very active in the Limousin. Many of the Resistance fighters took part in the liberation of Limoges itself (on August 21, 1944).

The Gothic Flamboyant architecture of the monumental Portail Saint Jean looks ethereal floodlit at night. Midway between here and the second of the two original cities are the enamel workshops, from the Boulevard de la Cite, through the Rue Raspail and dotted along the Rue des Tanneries. The craftsmen will happily explain their techniques, handed down from one generation to the next.

The second city is more extensive and its character more elusive. Because of large-scale town planning started in the XVIIIc by the intendants royaux (powerful regional administrators appointed by the King), its underlying mediaeval structure is only gradually being restored. This was the centre of political power, known as "the Chateau" - the Royal Town, ever at odds with the Bishop's City opposite. Limoges is an architectural melting pot, from the Jesuit severity of the XVIIc Gay-Lussac Chapel's main door, to the Art Deco surrealism of the Pavilion de Verdurier, a former cold store.

In counterpoint is Limoges' famed main railway station, crowned with its campanile and copper dome, like some latter-day mosque. Amid this curious medley one glimpses the mediaeval soul of the city, in the pedestrian precincts around the church of St Michel des Lions and the chapel of St Aurelien. The splendid Cour du Temple takes one back to the Renaissance, while other epochs are reflected in such features as the Presidial, the Fontaine des Barres square, and the picturesque quarter of the Ancestral Guild of Butchers.
