Thomas Archer’s magnificent baroque pavilion provides a focal point for the Great Garden, with formal rides radiating from it. It was built by Henry in 1709-11 to celebrate his elevation to the dukedom and was intended to be used as a banqueting house. The interior is decorated with trompe l’oeil imitating columns, statues and niches, by the Huguenot artist Louis Hauduroy. The pavilion has recently undergone a major programme of restoration, including repairs to the roof and conservation of the wall paintings.
