It is to an illegitimate daughter of Louis XIV that France owes the emblem of its legislative power, the National Assembly, which meets at the Palais Bourbon. It was in fact Louise-Françoise de Bourbon who decided to build this palace on the then marshy edges of the Seine. Next door, she commissioned the construction of a more modest palace for her lover, the Hôtel de Lassay, today the private residence of the President of the National Assembly.
