What are we waiting for to be happy?
It's 1937 and archaeologist Christiane Le Ray is about to begin excavations to establish whether Maillezais contains the remains of a Neolithic enclosure, like so many in the Vendée. She is enthusiastic. She had just discovered an Aurochs femur at the foot of the abbey, a sign that this animal was present. With the support of Achille Daroux, Member of Parliament and Mayor of Maillezais, she is going to try to recruit people to carry out the dig.

The Traveller and the Mad Architect
In 1834, Maillezais Abbey was owned by a farmer who was in debt and known to be the Abbey's demolisher. Madame Jousseaume, his mother-in-law, urged everyone she met to buy the remaining stones of the abbey. She needs the money to leave and change her life. Then a man raises his hand. He buys everything. He's a mad architect.
