Ancient Diocese of Agde Wikipedia
The former French Roman Catholic diocese of Agde existed from about the 6th century to the Concordat of 1801 between First Consul Napoleon Bonaparte and Pope Pius VII. Agde is in the south of France, in what is now the department of Hérault. The last bishop, Charles François de Rouvroy de Saint Simon Sandricourt, was guillotined in Paris on July 25, 1794.
The diocesan seat was the Cathedral of Saint-Étienne, originally dedicated to Saint Andrew. The cathedral was served by a Chapter, consisting of twelve Canons, including the Archdeacon, the Sacristan, the Precentor and the Treasurer. There were twelve chaplains (hebdomidarii), eight for daily services and four for requiems. There were thirty-two prebendaries. The diocese had only twenty-six parishes.The territory of the former diocese is now part of the diocese of Montpellier.
