Miglos is a commune in the Ariège department in southwestern France.

During the revolutionary period the municipality escaped fragmentation.

Château de Miglos: the ruins of this castle are perched on a limestone outcrop 750 metres (2,460 ft) high, a couple of kilometres upstream from the prehistoric caves at Niaux and the commune of Capoulet, in the valley of Vicdessos.

It was built towards the beginning of the 13th century, later razed by order of Cardinal Richelieu and largely damaged at the time of the French Revolution.

[4] In 1830, Jean-Louis Hycinthe de Vendômois, heir to the place, saw his residence plundered during the Guerre des Demoiselles (1829–1832) while opposing the peasants of Ariège with Charles X of France.
