Origin and history
Beaumont Castle, located in Agonges in the department of Allier (region Auvergne-Rhône-Alpes), was built in 1740 on the site of an old medieval castle, of which only a round tower remains. This classic ordinance monument consists of a central building body framed by two towers, completed by two symmetrical pavilions (a chapel and a billiard room) and commons. Its architecture reflects the influence of 18th century styles, with a terrace and subsequent additions like a hexagonal pavilion called "Chinese".
In 1850, the facade on the garden was modified by the addition of two front bodies accessible from the house body. At the beginning of the 19th century, the castle belonged to François Dalphonse, MP for Allier, who died there in 1821. The site, including the house, the pavilions, the dovecote and the communes, was listed at the Historic Monuments on December 13, 1978 for its architectural and historical interest.
The castle retains remarkable elements such as a circular dovecote, a fence wall with a perron, and furniture specially designed for the hexagonal pavilion, mentioned in an inventory of 1843. Although the garden-side windows disappeared, the building generally preserved its original appearance, reflecting the evolution of aristocratic residences between the 18th and 19th centuries.
