Vale Judeu is a toponym used in the area of Quarteira, in the surroundings of Vilamoura, and the exact origin of the name is not explained in a consensual way in the most accessible reference sources. The name has come to designate several points in the territory, beginning with Estrada de Vale Judeu – Quarteira, which structures addresses and nearby roads, as well as the former Vale Judeu railway halt, now closed, which once served the locality on the Algarve Line. In addition, the same name appears in public transport stops in the area, such as Vale Judeu (Igreja), establishing Vale Judeu as a practical reference for local orientation, even when the original reason for the toponym is not securely known.
