Château de Germolles, Gothic castle in Mellecey, France.

Château de Germolles is a rectangular residence surrounded by a water-filled moat, built around a closed courtyard in Mellecey, Saône-et-Loire. The south and east wings held the apartments, the west wing the reception rooms and the north wing the guards. The 13th-century lower chapel and wine cellar survive, and the entrance châtelet keeps two towers.

The site was held from the 13th century by the seigneurs of Germolles, whose maison-forte left the lower chapel and the wine cellar. Ruined by debt, Guillaume II ceded the seigneury around 1380; Philip the Bold recovered it in 1381 and gave it to his wife Margaret of Flanders, who from 1381 had it rebuilt over about ten years with Drouet de Dammartin, Jean de Marville, Claus Sluter and Jean de Beaumetz. Charles VI was received there on 12 February 1389.

The château's name comes from the seigneurs of Germolles, who held the site from the 13th century. Margaret of Flanders planted a large rose garden whose petals were sent to Flanders to be distilled into rose water, and she built a model sheepfold tied to the wool wealth of Flanders. The château holds the Maisons des illustres label, awarded in 2013.

The château is privately owned and visited on guided tours; the park and the building are shown together. It lies at Mellecey, about 11 km west of Chalon-sur-Saône and 30 km south of Beaune. A cultural season runs from October to June, so some rooms may be closed outside those months. The entrance porch, the barn and the grounds are protected as monuments historiques.

The castle preserves rare original decorations from the 14th century, including wall paintings with the letter M and thistles that represented Margaret of Flanders. These personal symbols of a former resident are seldom found elsewhere in this form.
