Like the Hôtel de Soubise, it was built in 1705 in the second Louis XIV style by P. -A. Delamair. Four cardinals of Rohan, prince-archbishops of Strasbourg, lived there. More prince than archbishop, the last was implicated in the affair of the Queen's Necklace (1785). In the right-hand courtyard, admire the quivering Chevaux du soleil by Robert Le Lorrain. The interior decoration of the apartments (wainscotting, upholstery, Cabinet des Singes by Christophe Huet) dates from 1750.

«Cathau la Borgnesse», lady's maid to Anne of Austria, having bestowed her favours on the young Louis XIV, was, as a sign of his royal appreciation, ennobled and enriched, as was her husband, Pierre Beauvais, without however having to earn the royal favour in so personal a manner. This sumptuous mansion was designed by Le Pautre. From the balcony, Anne of Austria and the Queen of England, watched Louis XIV's triumphal entry into Paris, and that of his wife, Marie-Thérèse, on 26th August 1660.

Famous for its second-hand book stores and its old book sellers, it links Saint-Michel Bridge to the Petit Pont Bridge.

In the apartment where Eugène Delacroix lived from 1858 to 1862, the main rooms serve as a setting for thematic exhibitions. An iron staircase gives access to his studio and the little garden, an unexpected complement.
