History

Tonnay-Boutonne developed around a fortified site known as the Tour de Ganne. Local heritage documentation identifies the town as a fortified settlement from the 12th century and describes the medieval fortifications, the seigneurial residence and the Saint-Pierre gate.

The town was taken by the forces of Louis IX during the campaign of 1242 against the Lusignan family and their allies. A study of the campaign places Tonnay-Boutonne among the fortified places taken by the royal army before the Battle of Taillebourg.

A local tradition connects the former donjon with Ganelon, the legendary traitor of Roncesvalles, and relates that he was captured by Charlemagne at Tonnay-Boutonne. The tradition is presented as a legend rather than established history by the local tourism authority.

The former donjon was demolished in 1839. The present-day Saint-Pierre gate is the principal surviving masonry element of the medieval fortifications.

Administration

Tonnay-Boutonne is part of the arrondissement and canton of Saint-Jean-d'Angély and belongs to Vals de Saintonge Communauté.

Places of interest

Saint-Martin's Church

The Saint-Martin's Church originated as a chapel associated with the former donjon, known as the Tour de Ganne, and later became the parish church. It was partly destroyed during the Wars of Religion, restored in 1638 and rebuilt in stages during the 19th century. A major rehabilitation was completed in 2003.

The church also contains protected movable heritage recorded in the French Ministry of Culture's Palissy database.

Saint-Pierre Gate

The Saint-Pierre Gate is a surviving element of the medieval fortifications. Built in the 14th century, it consists of a gateway between two round towers with machicolations. It is listed as a monument historique.

The gate was the principal northern entrance to the town and formed part of the fortifications surrounding the former castle site.

The L'Houmeau lock and a tree-lined riverside promenade along the Boutonne are also among the local heritage and recreational features described by the Vals de Saintonge tourism authority.

Culture

Tonnay Bon

Tonnay Bon is a contemporary music festival associated with the local association Objectifs Jeunes. The association was established in 1999 and promotes cultural activities in rural areas, including musical events and the festival. The festival dates from 2000 and has been held in Tonnay-Boutonne as a recurring music event.

Heraldry

The arms of Tonnay-Boutonne are blazoned: Azure, an old keep of the place Or on a mount Vert, a river Argent in base over which sails a galley Gules.

The arms depict the former keep and the Boutonne. The heraldic design places the green mount on a blue field, a combination described by the source as a heraldic fault.
