Saint Peter's Church

The church, dedicated to Saint Peter, stands in a secluded position between the town and the village of Veret. It was built between 1839 and 1841 in the neo-classical Sardinian style.
While the neighboring parishes of Nernier, Yvoire and Excenevex depended on the abbey of Filly, Messery was under the authority of the chapter of St Pierre-de-Genève, and appears to have little income.

As early as the 15th century, there was a confraternity of the Holy Spirit. The population then stood at 30, rising to 40 in 1518 and over 50 by the end of the 16th century. As a result, emigration began at the end of the previous century.

During the Bernese occupation, Nernier, until then a godchild of Yvoire, became part of Messery in 1540 and remained so until 1793. When the occupiers left, Messery was one of three parishes authorized to retain a Reformed minister.

In 1589, in the midst of a religious war, the Baron d'Hermance, governor of Allinges, authorized it to continue celebrating the Lord's Supper, preaching and baptizing, but the chroniclers point out that "there is no exercise in the whole baillage other than here". As a result, the village was spared from the Geneva troops that were ravaging the Chablais region at the time.

Similarly, after the mission of St. François de Sales, the parishes of Messery and Nernier, made up mainly of boatmen and fishermen, were reluctant to recant and, along with Yvoire, were among the last to convert. The behavior of the local nobility could only encourage them in this attitude.
