This neo-Gothic church was built to replace the dilapidated church of the Recollect Fathers, a men's convent founded in 1627. In the 19th century, the church wanted to encourage a revival of Catholic worship; it encouraged the construction of new religious buildings in Gironde. Thus, in 1856, the Saint-Géronce church was consecrated. Due to lack of space, its apse was oriented towards the south, contrary to what the liturgy provided. The organ, which has its original construction from 1861, is remarkable. Mass is celebrated there every Sunday morning at 10:00 a.m.

The Château de Thau is very old and known since the 12th century. It belongs to the defense line of the Côte Girondine. Set slightly back from the shore, it dominates the ebb and flow without showing itself, like a carpet behind thick groves. Here and there, the name of Thau comes and goes at the bend of a manuscript but it is at the beginning of the 1400s that historians find traces of the successive owners - the Math family, from 1400 to 1480, - the Sudre family 1540 , the Hague, then the President of the Parliament of Bordeaux, Louis de Grimard owned everything between 1680 and 1700… In 1700 we know the state of the place: “vast lower rooms, all well furnished and the walls decorated with vast series of tapestries”. Today, the Albert Schweitzer family owns and administers the estate which is the flagship of Gauriac. Facing the Médoc, a few steps from the Gironde estuary, 41 hectares of vineyards are planted with 40% Cabernet Sauvignon and 60% Merlot, on silty-limestone soil and extend over the Bourgeais region. The excellent geographical location allows the vineyard to benefit from favorable maturity criteria.

The small port of Plassac is typical of the esteys of the Gironde estuary. It is in the heart of the ancient village with a Gallo-Roman villa. A Terra Aventura route, combining hiking and discovery, allows you to get to know Plassac better. During your visit, you can also admire mosaics displayed in the alleys of the village: they were created by the inhabitants and by the Babylon Mosaic workshop-boutique. A stepped earthen dike made it possible to shape the current configuration of the port, making it possible to create 44 places reserved for pleasure craft. A rocky groyne protects the entrance to the port. 22 gangways provide access to the boats and boaters can benefit from a water tap, electrical outlets and a light point. https://www.bbte.fr/equipements-de-loisirs/port-de-plassac/
