25/ Luxembourg
This is a country that is worth a visit. Moreover, this country has many castles to visit. There is no particular number that can be shown. One of the courts open to tours is Vianden Castle. This is a feudal castle built on old Roman ruins. However, the castle is not the only historic building available for viewing. Visit the Grand Duke of Luxembourg's mansion to discover more exciting things.
Try the Cathedrale Notre-Dame, a grand Catholic church that appeared in the 17th century. Luxembourg has great architectural works: The Adolphe Bridge is a stone bridge built in the early 1900s that greets tourists for a short outing.
