At 230 metres above sea level, this castle was the HEADQUARTERS of the Order of Santiago for nearly 400 years (1443-1834) — from the battlements you can see Serra da Arrábida, the Sado estuary where dolphins swim, the Tróia peninsula, the Atlantic Ocean, and on clear September evenings, Lisbon 40km north. Walk uphill from the festival area (10-15 minutes) to Castelo de Palmela, where the Moorish fortress dates to the 8th-9th century and Afonso Henriques took it in 1147, the same year he conquered Lisbon. Go at 18:00-19:00 in early September for golden light on the vineyards below, and bring your glass of wine from the festival — drinking Castelão while looking at the vines that produced it is the kind of moment you remember.
🔄 BACKUP: If the castle is crowded during festival, come the next morning at opening — the light is different but the views are empty.
