The Roman theatre of Cádiz is an ancient structure discovered in 1980. The theatre, which was likely built during the 1st century BC and was one of the largest ever built in the Roman empire, was abandoned in the 4th century and, in the 13th century, a fortress was built on its ruins by order of King Alfonso X of Castile.
The theatre featured a cavea with a diameter of more than 120 meters, and could house some 10,000 spectators. The theatre was one of the few Roman structures of ancient Hispania mentioned by classical authors, including Cicero and Strabo. Excavations in the site have also found remains of a quarter dating to the taifa period, Almohad houses and 17th century pits.
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.
