Visit the outside of the castle of Grandville and the chapel: welcome by the owners; signposted route through the park; leaflets available. The castle and the commons were built in 1820 by Aristide de Grandville, deputy mayor of Port-Saint-Père and great friend of the famous lawyer Berryer who entrusted the realization of this neo-palladian villa to the architect Blon. The English park was designed by the landscape architect Noisette.
