There is a picnic table and you can take shelter here, but the whole area gives a somewhat run-down impression.

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 commune takes its name from its Latin name, Blacciacum. A Gallo-Roman settlement is attested by the discovery of the remains of three Gallo-Roman villas, dating from the 1st to the 5th century AD. These remains were found near the current site of the church, not far from the Gironde. During the medieval period, the village's center of activity seems to have shifted to the heights overlooking the river. This is evidenced in particular by a hoard of Merovingian coins discovered around 1850 at a place called Montuzet (Mont des Yeuses). The lower Plassac region, around the port, was heavily involved in river and maritime activity in the 17th, 18th, and 19th centuries. Merchants and ocean-going captains settled in beautiful stone residences. This river activity gradually declined in the 20th century.
