All these works ran the abbey into debt so Louis XVI. had it closed and placed in liquidation. The Revolution completed its ruin. Sold as national property, Châalis greatly suffered.
The buildings were for the greater part destroyed, the old church was sold piecemeal at the rate of twelve sous (6d.) per cartful of stones.
In the nineteenth century the successive proprietors did their utmost to reconstitute the domain. The grounds were bought back and the ruins consolidated. The abbatial building became a castle, and the park was laid out again. In 1902, Mme. Jacquemart-André bought the estate for 1,200,000 francs. She bequeathed it to the "Institut de France" with the museum that she had established in the castle. The "Institut" took possession of it in 1912, at the donor's death.
The Church.
The church, built at the beginning of the eighteenth century, is of great interest from an archæological point of view, for it shows the first application (by the Cistercians) of the Gothic style of architecture which had just made its appearance in the "Ile de France." In the hundreds of abbeys created by the original abbey of Cîteaux (situated near Dijon), the Roman style had hitherto held sway. Beginning with Châalis, the Cistercians proceeded to spread the pointed arch all over Europe, where soon more than 1,800 branch abbeys were scattered.
The church of Châalis was vast, measuring 269 feet by 89 feet.
Its transept (the ruins of the northern part are seen in the view on the preceding page) was remarkable for its enormous size, compared with that of the choir, and for the seven radial chapels—one of which is clearly visible on the right of the view—enclosed in each of its branches. An outline of the nave remains (on the left of the photograph); it had twelve bays, preceded by a porch. The steeple which rose from the tower was destroyed by lightning in the seventeenth century. The monastery was connected with the church, and the outline of the storied galleries is seen in the view below. The abbot's chapel appears in the middle distance, on the right of the view on the preceding page. It is designed in the style of the Sainte-Chapelle in Paris.
