She erected a church in honour of the Virgin, which should serve for a burial-place for her nuns; this was beyond the walls of her monastery, and a college of priests was added to it to supply religious instruction to her community.

The church was finished, and its foundress died in 587.

She was interred there by the celebrated Gregory of Tours.

The tomb, of the simplest construction of fine black marble, still exists in a subterranean chapel, the object of religious pilgrimages without end; and when, in the fourteenth century, it was opened by Jean, Duc de Berry, Count of Poitou, brother of Charles the Wise, the body was found in perfect preservation.

In 1562 the Protestants took possession of the church, and broke open the tomb, scattering and burning the bones; but some of them were, nevertheless, gathered together and replaced in the marble, which was joined by iron cramps, and does not exhibit much injury.
This huge mass of black marble has a very disgusting appearance, from being entirely covered (except at one little corner, kept clean to show its texture) with the runnings of the countless candles perched upon it by the pilgrims, who arrive in such crowds at some periods of the year, that the vault becomes so hot and close as to be unsafe to remain in long.
