Church of Saint-Cyr and Saint-Juliette of Pierre Ronde, Medieval church in Mesnil-en-Ouche, France.

The Saint-Cyr-et-Sainte-Julitte de Pierre Ronde Church features simple medieval architecture with a rectangular nave, a choir reconstructed in 1746, and a traditional slate bell tower characteristic of Norman ecclesiastical buildings.

Originally built in the 12th century and rebuilt in the 15th century, this parish church preserves original foundation remnants and represents multiple successive architectural periods spanning several centuries of construction.

The church is dedicated to Saints Cyr and Juliette, a child and his mother martyred around 304. Its name is recalled in local devotion, and visitors can see wall paintings in the nave and choir rather than frescoes: these were restored between 2015 and 2018, the nave paintings dating from the 15th century and the choir paintings from the 18th century.

The church is accessible via a hiking trail starting from Beaumesnil through the Castle Avenue, passing the cemetery and crossing the forest, providing a natural 35-minute walking approach.

Rediscovered in 1991 by members of an association after decades of neglect, the church was restored until 2023; its 15th-century nave paintings and 18th-century choir paintings were cleaned between 2015 and 2018. It was listed as a monument historique by decree of 17 December 2025.
