Founded in the year 1118, the L'Abbaye de Fontenay is one of the first monuments to have been selected by UNESCO in France, as a world heritage site. A former monastery, the L'Abbaye de Fontenay is spread over a vast area and nestled in the beautiful greens. The monument is now in ruins, however, taking a walk through the place pushes you back in the time of simplicity. To know more, check the website.
