The Hotel Lambert was built in 1640 by the architect Le Vau. Located on the Ile Saint-Louis, at No. 2 rue Saint Louis en l'île in the 4th arrondissement of Paris, he has a magnificent facade, a rotunda and a garden.
Early in age, Le Vau showed his immense qualities as an architect by building the most magnificent houses of the seventeenth century. The decoration of the interior asked five years to the painters Lebrun and Lesueur. The Lebrun's galerie d'Hercule prefigures the galerie des glaces at Versailles.
In 1975, the Hotel Lambert belonged to the Rothschild family until the death of Guy de Rothschild (2007), to be sold to a brother of the emir of Qatar (2007) who wanted to modernize it (elevators, air conditioning, garage dug in the garden). This renovation has encountered fierce opposition especially in the person of Jean-François Cabestan (patrimoine architect and lecturer at Paris I). The association Sauvegarde et Mise en valeur du Paris historique has filed three appeals to the Minister of Culture for suspension, cancellation and withdrawal of the decision which allowed the work.
In 2010, the Ministry of Culture has announced the signing of a mutual agreement between the emir of Qatar and the association Sauvegarde et Mise en valeur du Paris historique, represented by its president Pierre Housieaux. The memorandum of understanding will be signed rue de Valois in the presence of Minister of Culture Frederic Mitterrand, and end the dispute between the owner, Abdullah Bin Hamad Al-Thani and the association.
The City of Paris, which has its say on the outdoor of the Hotel Lambert, has also played an important conciliatory role.
