The Congress Column (French: Colonne du Congrès, Dutch: Congreskolom) is a monumental column in Brussels, Belgium, commemorating the creation of the Belgian Constitution by the National Congress of 1830–31. Inspired by Trajan's Column in Rome, it was erected between 1850 and 1859, on the initiative of the then-Prime Minister of Belgium, Charles Rogier, according to a design by the architect Joseph Poelaert. At the top of the column is a statue of Belgium's first monarch; King Leopold I, and at its base, the pedestal is surrounded by statues personifying the four freedoms guaranteed under the Constitution. The Belgian Tomb of the Unknown Soldier with an eternal flame lies at its foot.
