Estuna Church dates from the early 13th century or possibly the late 12th century. The structure of the building indicates that a tower was initially planned for the eastern end of the church but never built. It may have been intended as a defensive tower which became redundant as times became more peaceful as the Middle Ages progressed in Sweden.
The church has been rebuilt and expanded several times. During a renovation of the altar in 1733 a patch of parchment was discovered that noted the date of a re-inauguration of the church to 1298. This was probably done in connection with an enlargement of the church towards the west. The church porch was added during the 15th century. During a renovation in the 20th century, medieval frescoes were discovered and uncovered. Among the church furnishings, most date from the 18th century. The baptismal font is however older, from the 13th century. The elaborate crucifix was donated to the church in 1783 and made in Rome.
References: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.
