Very beautiful Romanesque church from the 12th century.

This road bridge was built by Gustave Eiffel, between 1879 and 1883, on the foundations of a first suspension bridge (1839-1869) carried away by a storm. Destroyed during the Second World War, it was rebuilt by his grandson. The access ramp is supported by stone arcades which, seen from below, have the appearance of a Gothic cathedral.

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.

The linguistic proximity of the "Pont Eiffel", which spans the Dordogne River here, and the low mountain range "Eifel" in the far west of Germany is no coincidence: The family of the designer - whose world-famous Tower of Paris (named after its builder) is probably known to everyone - has German roots. The ancestors of the Eiffel Tower builder Gustave EIFFEL come from the Eifel town of Marmagen (in the Euskirchen district, North Rhine-Westphalia). The village square there - if you are interested, see the following hiking highlight https://www.komoot.com/de-de/highlight/1830307 - is named after him.

Attention! It has been permanently closed since February 2024, because it is too old. It will be dismantled in 2025, and rebuilt in 2028. The planned diversions go through Guîtres or Savignac-de-l'Isle.
