Vila Real de Santo António is a city, civil parish, and municipality in the Algarve, Portugal. The population in 2011 was 19,156, in an area of 61.25 km². It is one of the few municipalities in Portugal without territorial continuity: its territory comprises two parts, with the municipal seat located in the eastern part. Both the city and the municipality are the southeasternmost of Portugal. Vila Real de Santo António was founded after the 1755 Lisbon earthquake, and largely expanded in 1774 using the same architectural and construction techniques employed in the reconstruction of Lisbon after the disaster.
