She accompanied her husband, the Marquis de Villars, into Spain, when he was appointed ambassador to that court, at the time Charles the IId. married Marie-Louisa d'Orleans, niece to Louis XIV. who was particularly attached to Mademoiselle de Villars, though the punctilious manners of the Spanish court, and the jealousy Charles entertained of the French nation, which could hardly bear she should converse with any of them, embittered the friendship that amiable princess entertained for her. During her stay at Madrid, she wrote many letters to her friends, particularly to Mademoiselle de Couiange, most of which have been preserved; they are written with great spirit, though not in the most elegant stile; but they contain a great number of curious anecdotes and entertaining observations, on the customs and manners of the Spanish court. Mademoiselle de Sévigné, in one of her letters to her daughter, says; "Madame de Villars has written a thousand agreeable things to Madame de Coulange. The Duke de Rochefoucault (who you know is very curious), Madame de Vins, and myself, are for ever at Madame de Coulange's elbow, to learn all we can."
