In 1624 the construction contract for the Palais du Luxembourg was withdrawn from Salomon de Brosse. On 26 March 1624, the Queen Mother's Council retroceded the contract to Marin de la Vallée for the completion of the palace. He intervened as master mason to realize the north-east wing according to the plans of Salomon de Brosse. These works were probably finished in spring 1626. On 1 April 1626, he signed a contract for the construction of the Petit Luxembourg and a wall separating the garden from the park. In June 1626, he signed a second contract for the completion of the courtyard of the palace with the paving of the terrace and its balustrade.Sara Galletti, Le palais du Luxembourg de Marie de Médicis 1611-1631, Éditions A. et J.
