The late 15th century Baia Castle was built by the over ancient Roman ruins thought to be the summer residence of Julius Caesar. On the 29th September 1538 the great eruption, with devastating effects for all the Phlegraean Fieldsi, caused serious damage to the Castle of Baia too. The castle was restored and enlarged by the viceroy don Pedro Alvarez de Toledo.
Today, this cliffside Aragonese castle with sea views is home to the Archaeological Museum of Campi Flegrei.
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.
