The building is of unique importance historically and architecturally as its choir, completed in 1144, shows the first use of all of the elements of Gothic architecture . </P> <P> The site originated as a Gallo - Roman cemetery in late Roman times . The archeological remains still lie beneath the cathedral; the people buried there seem to have had a faith that was a mix of Christian and pre-Christian beliefs and practices . Around 475 St. Genevieve purchased some land and built Saint - Denys de la Chapelle . In 636 on the orders of Dagobert I the relics of Saint Denis, a patron saint of France, were reinterred in the basilica . The relics of St - Denis, which had been transferred to the parish church of the town in 1795, were brought back again to the abbey in 1819 . </P>
