The Parish church of Saint-Julien was built on the site of the Château de Sennecey, constructed at the end of the 10th or beginning of the 11th century. The château was purchased by the municipality of Sennecey on August 29, 1824, and in 1825 the central building and the chapel were demolished. The contract for the construction of the new church was awarded in 1826, and the neoclassical church was consecrated on August 24, 1831, by the Bishop of Autun. Among its notable features are magnificent 19th- and 20th-century stained-glass windows framing the chancel and nave, a superbly sculpted pulpit, an Empire-style baptismal font, a 17th-century painting depicting the "Death of Saint Joseph," and a beautiful organ dating from 1899. The Parish church is open daily.
