This itinerary follows the very old Grand'rue, down the eastern slope of the promontory to the Clain river. Aligned with half-timbered houses, narrow freestone façades or fine town houses, this street structures most of the plateau, since it was for a long time the only access from east to west.
The blue path is an ideal first discovery of Poitiers' past. It brings you to some of the most prestigious buildings in the town : Notre-Dame-la-Grande, whose west-front is a masterpiece of Romanesque art; the former Ducal Palace (now Law Courts) and its splendid great hall (12th and 14th centuries); the Episcopal quarter, in which Saint-Johns baptistery, a witness of early Christian times, responds to the massive Gothic cathedral of Saint-Peters. Once in the lower city, you can still visit the church of Saint-Radegund, sheltering the tomb of the saint who founded first female abbey in the city in the 6th century.
