This town near the scenic Serra de Grândola belongs to Alentejo, which was home to many farm workers during the 19th and 20th centuries. The region was known for its choral songs, which were often sung by the workers while in the fields. The singer Zeca Afonso composed his song “Grândola, Vila Morena” in this style and had it broadcast during the night of April 25, 1974. This was the secret starting signal for the Carnation Revolution, which made the city famous throughout the world. Franz Joseph Degenhard later translated the text into German. When entering the town from the direction of Lisbon, you can still see a monument displaying the song's lyrics.
