This is not the abbey, but the parish church in the town of Fontevraud l'Abbaye.
The church of Saint Michel was built in about 1170 at the request of the abbess Audeburge of Fontevraud Abbey and built (or ar least paid for in part) by Henry II and his wife, Eleanor of Aquitaine. There are two heads carved into the vault of the choir near a rib which could be their likenesses. We haven't noticed these, even though I have taken a photo of them, so next time (and there is sure to be a next time) we are there we will report back.
This photo has a couple of interesting features: the heads which are supposedly those of Henry and Eleanor; and the blocked windows over the altar, which have subsequently plastered over and the whole wall painted to look like cut stone.
The church was expanded in the fifteenth and seventeenth centuries, but the Romanesque core of the building is still evident - the blocked up rounded windows in the above photo, for instance, and the generally half rounded rather than pointed arches. I don't know if the low porch all around the building as shown in the top photo is unique (or even particularly romanesque), but I do really like it.
where they were erected in 1621.
but I suspect it was also from the abbey.
