The Gallo-Roman Theater is an ancient arena theater located in Thénac, Charente-Maritime. It is part of an ancient rural sanctuary with thermal baths and a spring. Likely constructed during Nero's reign and abandoned in the 3rd century, its remains were classified as historical monuments in 1990.
Measuring at least 84m wide, its unique architecture involves internal buttresses defining compartments, reinforcing its structure against earth pressure.
The theater is part of a rural sanctuary 5 km south of Saintes, existing since the Neolithic era. Believed to be built during Nero's time, it remained in use until at least the 3rd to 4th century. After abandonment, it served as a stone quarry. Excavations occurred in 1825-1828 by René Eschassériaux, published later by his grandson Eugene in 1880-1881. Additional excavations took place in the 1960s and 1990s, leading to its classification as a historical monument.
The arena theater, at least 84m in diameter, features an east-facing cavea with a semi-circular orchestra, built from local Campanian limestone. Semi-cylindrical buttresses reinforce the cavea's perimeter against earth pressure. Radiating vomitories divide the cavea into six sectors. Recent studies reveal a fully masoned stage wall with two passageways leading to the orchestra. The theater has been municipally owned since 2000, previously belonging to the state for 14 years.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
