Fortified house of the noble family of Laconnex, whose volume and typical silhouette play an important role in the site. This square building, stocky and solid, covered with a four-sided roof and equipped with a staircase tower, is quite characteristic of the fortified buildings of the 15th century. Although the structural work dates back to this period, the fortified house was rebuilt or renovated several times following partial destruction. This was the case in 1573, when the mason Claude Coquens de Soral worked there: the hexagonal staircase tower is attributed to this site (but the mouths and the windows with braces would be reused). A Catholic chapel was added to the south corner in 1698, then replaced at the end of the 19th century by a buttress; in the 18th century, a round tower disappeared. A room on the ground floor has a ceiling with exposed beams and a monumental fireplace. Restorations in 1943 and 1963.
