Avenches (earlier known as Aventicum) became the capital of the Roman Helvetia province around 15-13 BC. The heyday of the city was in the 2nd century AD when it had over 20,000 inhabitants. The amphitheatre was also erected in the early 2th century. Today it is Switzerland's best preserved amphitheatre.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
