St. Radegonde was founded in the sixth century as a mortuary chapel for the Queen, St. Radegonde, who fled from her fierce husband, Clotaire I., and took the veil in the Abbey of St. Croix, where she died in 587, and has ever afterwards been venerated as patroness of Poitiers, her tomb becoming a place of pilgrimage. The chapel was made into a collegiate church, and was reconstructed in the eleventh century and consecrated in 1099. There is a beautiful Flamboyant west doorway, with empty niches, and the north and south entrances are of the thirteenth and fourteenth centuries. On the right of the nave is the Chapelle du Pas de Dieu, having an old tomb, with two statues, showing the apparition of Christ to St. Radegonde, the impression of Christ’s foot being left on a stone between the two figures. The crypt in the centre of the church contains the tomb of St. Radegonde, an empty sarcophagus of black marble, reposing on a massive table of the twelfth century. The Church of Montierneuf (= _monastère neuf_) belonged to an eleventh-century abbey. The Romanesque choir was altered in the thirteenth century, with the addition of a central apse, known as ‘La Lanterne.’ It was mutilated during the religious wars, and has since been badly restored, but retains some remarkable eleventh-century work. The Temple of St. John (or Baptistère St. Jean)--_concierge to be found at Atelier St. Jean-Baptiste, No. 7, Boulevard du Pont-Neuf_--is perhaps the oldest Christian building in France, and is one of the chief relics of Roman Poitiers, having been built between A.D. 320 and 330. It is constructed of brick and stone, has straight-sided arches in the south end (the building is oblong, and faces north and south), and altogether an exceedingly Roman appearance. There is a low twelfth-century tower, and the interior is enriched with paintings of the same period. An interesting collection of Early Christian tombs found near the Pierre Levée, outside the town, is now kept inside the building. Pierre Levée is the name given to a recumbent monolith resting on three supporting stones, which tilt up one end, two others having disappeared since the seventeenth century. It is a short distance beyond the Pont-Neuf, in the suburb called St. Saturnin, east of the River Clain, and although the stone bears a Gaulish inscription, it is not easy to give its age. The Palais de Justice includes the ancient palace of the Dukes of Aquitaine and the Counts of Poitiers. The splendid hall, now the _Salle des Pas-Perdus_, has Romanesque and Gothic walls, with a similar wooden ceiling to that in the Palais de Justice at Rouen. The end wall, the work of Jean de Berry (died 1416), has three fireplaces with chimneys outside blocking the windows, which are filled with coloured glass. The keep, called the _Tour Marbergeon_, was built in the fifteenth century by Jean de Berry, and has four towers, ornamented with statues of the Counts of Poitiers.
