As garden fashions changed, in 1781 parts of the park were remodeled into a more traditional English landscape style by the Scottish landscape gardener Thomas Blaikie. In 1787, a new city wall, the Wall of the Farmers-General, was built along the northern edge of the garden, along with a circular rotunda in the form of a classical Doric temple, known as the Pavilion de Chartres, designed by Claude Nicolas Ledoux. The ground floor of the temple was used as a customs house, while the upper floor was an apartment with a view of the garden reserved for the Duke.
