Château de la Chassaigne, Medieval castle in Thiers, France.

Château de la Chassaigne is a pale rendered stone building with a dark brown tiled roof, located in Thiers, Puy-de-Dôme. A taller polygonal tower with a pyramidal roof and finial stands on the left; the main facade extends right under a hipped roof, with a low wall and a stone gateway bearing a carved urn in front. Windows have light surrounds, one upper left window is round-arched, others are rectangular with dark shutters, and a small balcony sits on the facade. A patch of pale purple flowering plants grows against the tower wall.

The property was built originally in the 15th century and underwent significant changes during the 18th century. During the French Revolution, the Montmorin family, former paper manufacturers who had gained nobility, had the castle towers dismantled.

The chapel inside holds wall paintings created across different time periods, showing artistic styles from the Gothic era up through the 1700s.

The château stands in the commune of Thiers, in the Puy-de-Dôme department of the Auvergne-Rhône-Alpes region. The grounds are laid out as a set of English-style gardens, so allow time to walk the park rather than only the building. The sources give no opening times or visitor arrangements, so check locally before travelling.

The towers that once stood here were pulled down during the Revolution by the Montmorin family, ennobled paper manufacturers of Thiers. The Louis XIV-style panelling on the second floor survived, though the château lost part of its woodwork in the 20th century. The chapel at one end of the gallery keeps murals ranging from the Gothic period to the 18th century.
