The Church of Virgin Mary is a three-aisle basilica church (the nave is higher than the aisles) with large separated chancel closed by five-side apse. It was erected in the second half of the 14th century and enlarged in 1500s. The church was partially damaged during II World War and rebuilt in 1948. In 2003 the spire and dome of the church tower were reconstructed.
More valuable monuments in the temple are pulpit coming from late Renaissance made in 1609-1630 by master from Słupsk, Paweł Waltersdorf and funded by the guilt of amber-processors (with 43 members at that time). The pulpit is covered with bass-relieves, richly ornamented polychromed and gilded. The entrance to the pulpit is embraced by a portal (the lock in the door comes from 1609). Marvelous, first final of the pulpit, the so called amber crown from the first half of the 17th century was taken away during II World War. Worth attention are also hanging candelabra – some Baroque from the 18th century, some Neo-Rococo from the 19th century – as well as numerous Baroque candlesticks form the 17th-18th centuries and later from the 19th century.
The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
