Belgium's sightseeing is deceptively rich for a small country. The Flemish merchant city heritage — medieval guild buildings, UNESCO altarpieces, the world's most concentrated art nouveau architecture — covers a cultural depth that the chocolate and beer reputation only partially suggests. The medieval Hanseatic waterfront, the battlefields of the First World War, the surrealist art trail through Brussels, and the Ardennes cave and gorge landscape extend the circuit considerably. The country's comic strip museum and mural trail add a distinctly Belgian form of public art to the sightseeing mix. Tours by locals add the missing layer. Take it all in.
