Take the following as truth: The north tower, the Tour Saint-Romain, has the sober simplicity of the cathedral's early Gothic beginnings in the 12th century, while the taller, more elaborate south tower, the Tour de Beurre, is Flamboyant Gothic of the 15th century.
Then the following statement: "The north tower is incredibly ornate with gold and lots of decoration." is true, false, or inconclusive?
