Francois Mathieu Mole (1705-1793), Chairman of the Parliament of Paris, did redesign the Renaissance castle and replant the park, it's said that it was on the advice of the naturalist Georges-Louis Buffon (1707-1788). Looted during the Revolution, the gardens were redesigned in 1846 by Louis Varé Sulpice (1808-1883). Now owned by the town, the castle park, covering an area of twenty-seven hectares, offers the public its majestic spaces deployed around large ornamental ponds. Recently renovated, the botanical garden experiment, created by landscape architect Pascal Cribier in 1999 around the water cycle, is open to the public.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
