 By 1002, the ruin of the previous building had been razed and construction began on a new Romanesque structure designed by William, consisting of a subterranean church round the sarcophagus of Benignus, a ground floor church for worship, and a rotunda, 17 metres in diameter, on three levels in the place of the apse, linking the two.Dedicated in 1016 by Lambert I, this suite of buildings was decorated in the ornate Cluniac style, of which only a few traces survive.In 1137 a fire destroyed most of the town of Dijon and damaged the monastery and its church.
