THE +
The phrase "castle in the sky" first appeared in the 1500s. The phrase may have derived from the original "to build castles in Spain." Much of Spain was under Moorish authority, so the concept of constructing a castle there was an impossible dream.
The original phrase was first used in the 13th century in Le Roman de la Rose. In 1365, it was translated into English from the original French.
