The Château de Sainte-Mère is a 13th-century ruined castle in the commune of Sainte-Mère. The castle was built at the time of the Treaty of Amiens (1279) by the Bishop of Lectoure, Géraud de Monlezun. It defended the frontier of the English possessions. The castle had a rectangular shape, with two towers attached to the north facade.
References:Saint-Émilion is a picturesque medieval village renowned for its well-preserved architecture and vineyards. The town and surrounding vineyards was made a UNESCO World Heritage Site in 1999, owing to its long, living history of wine-making, Romanesque churches and ruins stretching all along steep and narrow streets.
An oppidum was built on the hill overlooking the present-day city in Gaulish times, before the regions was annexed by Augustus in 27 BC. The Romans planted vineyards in what was to become Saint-Émilion as early as the 2nd century. In the 4th century, the Latin poet Ausonius lauded the fruit of the bountiful vine.
Because the region was located on the route of the Camino de Santiago, many monasteries and churches were built during the Middle Ages, and in 1199, while under Plantagenet rule, the town was granted full rights.
