The Basilique Saint Seurin is classified as a World Heritage Site by UNESCO. Dated as far back as the 6th Century, the originally Romaneque church as been added on over the years, including a major Gothic facelift starting in the 15th Century. The Crypt is open from 14:00 to 19:00 and dates back to the 4th Century. Considered Bordeaux's oldest church.
Another interesting church is Basilique St-Seurin, place des Martyrs de la Resistance whose most ancient sections, such as its crypt, date from the 5th century. See the porch leftover from an earlier church; it has some capitals from the Romanesque era.
This 11th century church has undergone frequent renovations, but its hidden treasure lies under its nave. A necroplolis harbours 6th century frescos and sarcophagus examples of early Christian art
