Château de Peufeilhoux, Medieval castle in Vallon-en-Sully, France.

Château de Peufeilhoux is a neogothic castle above the Cher and Aumance valleys, facing the Tronçais forest. Its Burgundian Renaissance facade has a double row of mullioned windows, and towers, turrets and a chapel with a hipped roof and square bell turret complete the building. A keep and a lower courtyard form the older core.

Construction of the castle dates from the early Middle Ages, when it consisted of a keep and a lower courtyard. Around the 14th century, wood was replaced by pink sandstone from nearby quarries. In 1675 it passed to Durand Villatte, lord of Courtines, whose family held it until 1900, when it was gradually abandoned in favour of the Château des Modières. It was bought and restored from 1920, and in 2013 it was acquired by Claude Thévenin.

The castle houses a "museum of explorers" with collections of insects, seashells, minerals and taxidermied animals. The building itself mixes a neo-Gothic style with a Burgundian Renaissance facade of two rows of mullioned windows, plus towers, turrets and a chapel with a hipped roof topped by a square bell turret with a bartizan.

The castle stands above the Cher and Aumance valleys and the Tronçais forest, so the approach is uphill. The whole complex, with its double enclosure, gateways and outbuildings, has been inscribed as a monument historique since 4 January 2021. The explorer museum inside holds insects, shells, minerals and taxidermied animals.

Inside the castle sits a cabinet of curiosities filled with hunting trophies, dried insects, and seashells collected by former owners over time. This unusual assemblage offers insight into the hobbies and interests of people from a bygone era.
