Of the parish church Saint-Pierre de La Gravelle, desecrated and sold in 1832, only the remains of the walls and the western portal visible from the road remain.
It is dated to the second half of the 12th century. Its original portal is "characteristic of small Romanesque buildings. The semicircular arch is bordered by a cymaise loaded with stars". Since 1832, it has been privately owned.
The central painting of the main altar, representing Saint-Pierre-aux-Liens, was transferred to the church of La Chapelle-Haute-Grue. The other objects of worship were moved to the church in Tortisambert.
In August 1900, the church of Montviette was enlarged by a porch belfry. On the south side, it is illuminated by a stained glass window representing Saint Peter, thus recalling the attachment of La Gravelle to the parish of Montviette.
