Besides the Hôtel Lambert and the Château de Vaux, we are indebted to him for the design for the Collège des Quatre-Nations, now the Palace of the Institute; the Maison Bautru, called by Sauvai "La Gentille," and engraved by Marot; the Hôtel de Pons, in the Rue du Colombier (to-day the Rue du Vieux-Colombier), built for President Tambruneau; the Hôtel Deshameaux, which, according to Sauvai, had an Italian room; the Hôtel d'Hesselin in the He Saint-Louis; the Hôtel de Rohan, in the Rue de l'Université; the Château de Livry, since known as Le Rainey, built for the Intendant of Finances, Bordier; the Château de Seignelay; a château near Troyes; and the Château de Bercy.[5]

We may add that Louis Levau, having become first architect to the King, succeeded Gamard in directing the works of the church of Saint-Sulpice, and that he, in his turn, was succeeded by Daniel Gillard in 1660.[6]

Louis Levau died in Paris. His body was carried to the church of Saint-Germain-l'Auxerrois, his parish church, on Saturday, the nth October, 1670, as attested by the register of this church. There, under the above date, may be read: "On the said day was buried Messire Louys Levau, aged 57 or thereabouts, who died this morning at three o'clock. In his life a Councillor of the King in his Council, general Superintendent of His Majesty's buildings, first Architect of his buildings, Secretary to His Majesty and the House and Crown of France, etc., taken from the Rue des Fossés, from the ancient Hôtel de Longueville."[7]

In the Archives de l'Art français (Vol. I) there is a document relating to Louis Levau:

"There has been submitted to us the plan and elevation of the building of the Cathedral Church of Saint-Pierre of Nantes, of which the part not already constructed is marked in red. This church is one hundred and eleven feet high from the floor to the keystones of the vaults at the meeting of the diagonals, and the lower aisles and chapels are fifty-six feet, measured also from the floor.

"It is desired to finish the said church, and to respect its symmetry as far as may be, and to make the lower aisles and chapels around the choir like those which are on the right of the nave.

"The difficulty is that, in order to finish this work, it is necessary to pull down the walls of the town, and to carry it out into the moat, and it is desirable to take as little ground as can be, in order not to diminish too greatly the breadth of the moat. Wherefore it is proposed to do away with the three chapels behind the choir, marked by the letter H.

"But, if those three chapels are removed, it will be seen that the flying buttresses which support the choir will not have the same thrust as those which support the nave; the strength of these buttresses will be diminished, and the symmetry of the church destroyed, in a place where the church is most visible.

"With this plan we send the elevation of the pillars and buttresses to show how they are constructed in the neighborhood of the nave.

"The whole of this is in order to ascertain whether the three chapels can be dispensed with, and the safety of the choir and the whole edifice secured."
