Origin and history
Mortillon Castle, located in Coulanges in the Allier department, finds its origins in a feudal mansion whose motte is still visible east of the current building. This site, initially defensive, was profoundly redesigned in the early 16th century, marking a transition to a more residential architecture. The house body, rectangular and composed of two levels, undergoes additional modifications in the seventeenth century, although its roof has been restored more recently. The most notable remains of its medieval period remain the two round towers of the 15th century, characterized by their slender conical roofs and their modest openings, integrated into the present façade.
The designation of the castle as a historical monument in 2010 allowed for the protection of the entire building, including its interiors and decorations, as well as the soil of the surrounding plots (B 449 to 451). This classification underscores the heritage value of a building that illustrates the architectural evolution between the Middle Ages and the modern era, combining defensive elements inherited from the 15th century and residential developments of the following centuries. The location of the castle, in a preserved rural setting, reinforces its historical and landscape interest, although the available sources do not specify its current use (visits, accommodation, etc.).
The archives mention a location accuracy deemed "a priori satisfactory" (level 6/10), with an address recorded in the Merimée database under the code Insee 03086, attached to the commune of Coulanges. However, no information is provided on any owners, sponsors or significant events related to the monument, outside the construction and protection periods. The round, lighted towers recall the military origin of the site, while subsequent transformations reflect the adaptation to the needs of a local nobility in search of comfort in the seventeenth century.
