The Belgium 2006 Brussels Atomium 2 euro commemorative coin celebrates one of the most iconic structures in the nation’s capital. The national side features a detailed depiction of the Atomium, the landmark originally constructed for the 1958 Brussels World’s Fair. Designed by engineer André Waterkeyn, the structure represents an iron crystal magnified 165 billion times, symbolising the scientific progress and peaceful use of atomic energy that defined the post-war era. By choosing this architectural marvel, Belgium commemorates its role as a centre for European innovation and international cooperation. The design also includes the royal monogram of King Albert II and the year of issue, reflecting the country's constitutional monarchy. This standard circulation coin was issued in 2006 with a mintage of 5,000,000 pieces.
