Sallertaine hosts two churches, both dedicated to Saint Martin. The new one got consecrated in 1911, while the old one is in the village since 900 years. It was erected within the 11th and modified in the 12th century. Following a document from 1136 the church was in the ownership of the Monastery of Marmoutiers (Tours).

Today the church is deconsecrated and is used by the local Tourist Office.

Visitors are welcome to find the interesting, rough carvings inside. Here are two birds drinking chalice. A very old icon, that in In Christianity it developed into an Eucharistic symbol, associated with Baptism and Resurrection.
