Whether it's the glistening diamonds of the Belgian district of Antwerp, the educative battlefields and trench museums from the second world war, or the chocolate-dominated window displays that line the towns, Belgium has a wealth of historical, cultural, and gastronomical significance. From the picture perfect castles sprinkled across the landscape, making Belgium a country with the world's greatest number of castles per square meter, to spectacular caverns and underwater systems, Belgium offers an abundance of experiences. Renowned for its medieval and baroque architectural excellences, museums in Brussels, Ghent, Brugge, Charleroi and Liège showcase the country's eclectic mix of styles and contributions to the Art Nouveau style.
