Origin and history
The house located at 24 rue du Petit-Fort in Dinan, Brittany, is an emblematic building of the medieval heritage of the city. Classified as a Historical Monument by order of 10 March 1938, it is also known as the House known as the Governor or Former Ganne Castle. This building illustrates the civil architecture of the late Middle Ages, with structural elements typical of this period.
A dendrochronological study conducted in 2022 by Valentine Guillevic gave a precise date for the implementation of wood on the facade and floors in spring 1506. This scientific analysis confirms that construction took place in the 15th century, an era marked by the urban and architectural development of Dinan, a strategic city in Brittany. The house, now owned by the commune, bears witness to the importance of bourgeois or seigneurial residences in the local historical fabric.
The location of the house, although specified by the official address (24 rue du Petit-Fort), has a geographical accuracy considered fair (note of 5/10). This monument, open to potential uses such as visiting or renting, remains a significant example of Breton built heritage, combining history and traditional constructive techniques. Its classification in 1938 underscores its heritage value and its role in Dinan's collective memory.
