Attached to the castle, the 13th-century church was burned down in the 15th century. Rebuilt, it was consecrated in 1539. The lords of Oysonville could pass from the castle to the church through a door opening onto a platform at the back of the church without mixing with the people. The altarpiece, the churchwarden's pew and the pulpit are from the 18th century. In the 19th century, the paneling of the nave was replaced by a plaster vault. Many tombstones are visible.

The tower of the church of Sainville, as well as the choir and the first three bays of the main nave, are in the Transitional Romanesque style from the end of the 12th century; the rest of the main nave and the side aisles appear to date only from the 15th century. The bell tower contains three bells. The largest, listed as a historic monument, is engraved with a quatrain: "Founded smokes all new I am the Patron of Sainville, I bear the name of St. Peter. In the year 1014. XLIX." (1549) The second, from 1821, bears this inscription: "Blessed be the Lord God of Israel, for he has visited and redeemed his people." Gospel of Saint Luke, chapter 1, verse 68. The third is located above the other two.

A village of medieval origin, Rochefort en Yvelines is well worth a little detour, as the town has retained its picturesque character with its old houses and cobbled streets, and in its center the small market square, a quiet spot near the bakery with a fountain. The most curious, and the bravest, will go up (on foot) to the church which overlooks the town and the forest. You will also see the remains of the fortified castle hidden in the woods.
