In the town centre, the parish church of St-Pierre dates from 1630 according to Baudiau, but from the first half of the 16th century according to the Mérimée database. The old parish church of St-Denis was located within the walls of the Château de Thoisy, "adjoining the château of which it formed the south wing". Today, a barn occupies its location according to the Cecab. The current church was remodelled or "repaired" in the 18th century (1758) by the priest Poncerot. The current church has kept its architecture, on a rectangular plan with a hexagonal apse, a wooden barrel vault of the nave, an original off-centre bell tower which makes the slate roof asymmetrical on the façade. In addition, it houses very beautiful frescoes. The cemetery has remained around it.
