Château de Beaulon, Renaissance castle in Saint-Dizant-du-Gua, France

Château de Beaulon is a Louis XII and Renaissance-style building whose north facade shows the original construction: a main block under a steep slate roof with two gables, and two dormers of very different design. The left dormer, a major element, marks the transition from late Gothic to French Renaissance, its pointed gable replaced by a round arch against the dark slate. Later buildings flank the main block.

The seigneurie of Beaulon was created by a 1503 transaction between Jean de Belleville and the Tartarin siblings, and the logis was built shortly after, not in 1480. In the 17th century the estate passed to the Nesmond family and is generally held to have served as a summer residence of the Bishops of Bordeaux. It was inscribed as a monument historique on 16 December 1987, and the park entered the pre-inventory in 1990.

The park's name Fontaines Bleues refers to artesian springs whose water shows an unusual blue hue, met along the paths of the garden. The garden carries the label Jardin remarquable, and the estate also holds a round dovecote with a conical roof dated 1740, pierced with 1,500 nesting holes.

The château, gardens and landscape park are privately owned and open to visitors; the park holds the Remarkable Garden label and the Fontaines Bleues lie within it. The gardens were replanted after the 1999 storm felled hundreds of trees, so expect young growth in parts of the park.
