☰Cathedral of St. Michael and St. Gudula

Brussels's twin-towered Gothic cathedral rises on the slope between the lower and upper towns, begun in the 13th century and finished some 300 years later. Dedicated to the city's patron saints, it is the stage for Belgian royal weddings and state funerals; inside, look for the vivid 16th-century stained glass and the over-scaled baroque pulpit carved with Adam and Eve being driven from Eden.
