Things to see and do Pierres

If only by curiosity, it is interesting to go to Stones to admire the Astronomical Observatory which is installed in this small village. It is marked as early as the entrance into the village, both its dome exceeds the low houses and the farms located in this corner of the valley of the Eure. In fact, the Centre, located at the top of a disused water castle, is used by the cultural recreation and recreation centre of Maintenon.
