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.

Construction of this neo-Gothic church began in 1892. On December 8, 1895, it was inaugurated and blessed, becoming the parish church in place of the Church of Saint Rémy. However, sculptures and stained-glass windows have been added or renewed to this day. The stained-glass windows in the nave depict the Beatitudes. Seven sculpted groups in the heart of the church symbolize the sacraments.

The church of Bleury, dedicated to Saint Martin, probably dates from the end of the Middle Ages. It was remodeled and enlarged in the 16th century by the addition of a large chapel on the north side. The nave ends with a semicircular apse. The chapel to the north is extended by a square bell tower which once opened onto the nave through an arch that is now blocked but still visible. The chapel opens onto the nave through two pointed arches made of recently rendered clotted stone. It communicated with the ground floor of the courtyard through an arch that is now closed. Another filled-in arch appears on the wall between the chapel and the lower room of the courtyard. The church is covered with a paneled roof. A single beam is sculpted, the penultimate one on the west side. It supported, with the beam resting on the facade wall, a recently demolished gallery. Some of the nave's semi-circular windows are late, and the pointed arch openings have Gothic tracery. The square bell tower has a saddleback roof. It is pierced with pointed arch openings. Access to the building is from the south, under a modern porch that houses a portal surmounted by a shield with three fleurs-de-lis. A stone cornice runs under the roof to the south, supported by unsculpted modillions. Two 18th-century altarpieces were included in the Supplementary Inventory of Historic Monuments on June 17, 1975. 16th-century wall paintings depict the Mass of Saint Gregory. They were discovered in 1881 and classified as Historic Monuments on November 17, 1908. Their preservation is currently threatened by infiltration due to the poor condition of the roof structure. The Sauvegarde de l’Art Français provided aid of 75,000 F in 1994, thus contributing to the repairs undertaken to restore the framework, which will allow the walls to be cleaned up.

Built in 1882 by the Marquis Armand de Pomereu d'Aligre, to be the "model farm" of Baronville, as well as the marquis' stables, this complex was subsequently constantly used for both agricultural and equestrian purposes. Used as the “Baronville Horse Riding Club” during the 1980s and 1990s, it was the setting for horse racing training and competitions welcoming personalities from the equestrian or artistic world, such as Jean Rochefort.

The building is dated from the 13th century and 16th century. The fortified farm was rebuilt at the end of the 16th century and served as a stately home. From the 17th century until 1970 the building was a farm and then housed a horse riding center and a restaurant. The farm is classified as historical monuments by a decree of July 11, 1975: the facades and roofs are affected by this decree. The municipality bought the building by asserting its right of pre-emption in 2005.
