The twelfth century Agen Cathedral, dedicated to Saint Caprasius, is one of the few large churches in France with a double nave, a regional trait also found in the Church of the Jacobins in nearby Toulouse.
The Saint Hilaire church, dedicated to the theme of the Holy Trinity which the Saint in question did a lot to defend, is notable for its unusual statues in front of the Church - Moses on the right, and St Peter on the left.
