Gerulata was a Roman military camp located near today's Rusovce, a borough of Bratislava. It was part of the Roman province Pannonia and built in the 2nd century as a part of the Limes Romanus system. It was abandoned in the 4th century, when Roman legions withdrew from Pannonia.
Today there is a museum, which is part of the Bratislava City Museum. The most preserved object is a quadrilateral building 30 metres long and 30 metres wide, with 2.4 metre thick walls.
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.
