Château de Séran, 18th-century castle in Massac-Séran, France.

Château de Séran is a pale yellow three-storey building in Louis XV style, with a central projecting section topped by a steep brown tiled pyramidal roof. Above an ornate wrought-iron balcony with scrollwork sits a triangular pediment, and a white balustrade with two arched openings runs at the base of the roof. The flanking wings have shuttered windows, some with light green shutters, and two square stone gate pillars with a low iron fence stand in front. The main building dates from about 1803 and is flanked by two wings forming outbuildings.

The building is cited in an 1865 archaeological inventory of the Tarn and appears on the 1824 cadastral map; it is dated to 1803. Gustave Daguilhon-Pujol, attorney general in Toulouse and deputy of the Tarn, retired here and died at Séran on 25 December 1882. His son Charles, first president of the Pau court of appeal and mayor of Séran, died here on 27 December 1914. In 1921 the property passed through Laure Daguilhon-Pujol, widow of the Duke of Montebello, to the Juge-Montespieu family.

In September 1936, Mme de Juge-Montespieu gave a ball at the château marking the end of the South-West manoeuvres, helped by her daughters Mrs Nicholson and Miss Lorisande Walker; colonels, commanders, counts and barons attended. Earlier, on 1 September 1934, during the Lavaur horse show, she held a dinner-dance there. Marcia Mansel, a British nurse twice awarded the Croix de Guerre, settled at Séran in 1920 and married François de Juge-Montespieu, an officer and show-jumping champion.

The castle is private and divided into 13 lots held in co-ownership since 2006, so it can only be seen from outside. It stands 5 km from Lavaur, near the departmental road to Castres. The west building destroyed by fire on 9 March 2014 was rebuilt after several months of works.

The château was squatted by the Compagnie Royal de luxe from late 1984 until 1990, after the street-theatre company left Saint-Jean-du-Gard; it then moved to Nantes. In 1995 the SCI Château Seran bought the partly ruined building and divided the main house and outbuildings into 13 lots sold as a co-ownership, a division still in place.
