Valldemossa (in Catalan) or Valldemosa (in Spanish) is a village and municipality on the island of Majorca, part of the Spanish autonomous community of the Balearic Islands.
Valldemossa is famous for one landmark: the Royal Charterhouse of Valldemossa, built at the beginning of the 14th century, when the mystic and philosopher Ramon Llull lived in this area of Majorca.
In the 1830s the Spanish government confiscated monasteries, and the historic estate was sold to private owners, who have since hosted some prominent guests. These have included the Polish composer Frédéric Chopin and the French writer and pioneering feminist George Sand (who wrote a notable account of A Winter in Majorca, describing their 1838–39 visit and praising the island's natural beauty but criticizing what she perceived as the prejudice and vices of the natives).
