Carcavelos, a region demarcated in 1908, is located very close to the mouth of the Tagus in the Parishes of S. Domingos de Rana and Carcavelos in the Municipality of Cascais and part of the Parish of Oeiras in the municipality of the same name.

The fame of Carcavelos wines is lost in time. The Marquis of Pombal, who produced them on his estate in Oeiras, appreciated them so much that King José I presented them as a gift to the court of Beijing in 1752.

Wine production was the most important economic activity in the parish of Carcavelos for centuries. Its centuries-old name, quality, and typical characteristics were recognized by a Legislative Charter in 1908.
