Hôtel de Nevers (left bank)
The Hôtel de Nevers (French pronunciation: [otɛl də nəvɛʁ]), later the Hôtel de Guénégaud ([- ɡeneɡo]), then the Hôtel de Conti, was a French aristocratic townhouse (hôtel particulier), which was located on the Quai de Nevers (now the Quai de Conti), just east of the former Tour de Nesle on the site of the present day Hôtel des Monnaies in the 6th arrondissement of Paris. Construction began in 1580 to the designs of an unknown architect for Louis Gonzaga, Duke of Nevers, although it was never completed as intended.
