Église Sainte-Eugénie de Solférino, Roman Catholic church in Solférino, France.

Église Sainte-Eugénie de Solférino is a neo-Romanesque church of pale stone with a single rectangular nave under an exposed timber roof, lit by eight round-arched lancet windows and a polylobed rose window on the eastern gable. The western gable carries a small square bell tower with an octagonal slate spire and cross; a sacristy leans against the eastern end, and a tribune overlooks the rear wall.

Built between 1859 and 1860 with funding from Napoleon III to serve his imperial estate of Solférino, founded in 1857. The date 1860 is confirmed by a medallion above the entrance porch inside. It became a succursal parish in 1862 and stayed in imperial hands until 1905, when the empress sold it to Mr Lebert. Bought back by Mme Schneider in August 1920, it was restored, remained private until 1993, when the owners ceded it to the commune for a symbolic franc, and was reopened by Bishop Robert Sarrabère of Dax on 12 March 1995 after works funded by the EU, the Ministry of Culture, the Landes department council and the parish committee.

The dedication to Saint Eugenie of Rome honours Empress Eugenie de Montijo, wife of Napoleon III. The motto "Aratro et Altari" ("By the Plough and by the Altar") was given to the imperial estate by Abbe Cazeaux, the first parish priest, on 7 October 1863 in the Emperor's presence. The window above the altar shows wheat, sunflower, oak acorn, maize, grape and pine cone.

The building was privately owned until 1993, when it transferred to municipal care and became open to the public. Visitors should check locally about opening times, as access may vary depending on services or events.

A stained glass window above the altar displays the motto 'Aratro et Altari', representing the bond between farming and spiritual life. This artistic detail embodies the special connection between land and faith that defined the estate.
