Castro Marim Castle
Castro Marim, Portugal
A castle above the salt pans of the Guadiana estuary, once the seat of the Order of Christ. Flamingos feed in the nature reserve around the town.
The castle of Castro Marim stands on a hill on the east bank of the Guadiana, within the Sapal de Castro Marim nature reserve. After the area was finally recaptured from the Moors in 1242, King Dinis strengthened the fortifications. In 1319 the pope gave the town to the newly founded Order of Christ, which made it its first headquarters; in 1334 the order moved to Tomar. The 1755 earthquake destroyed the old town inside the walls, and the settlement was rebuilt outside them. The surrounding landscape is shaped by salt pans where fleur de sel is still harvested by hand.
The reserve was founded in 1975 and covers more than 2,000 hectares. Flamingos are the best-known residents, alongside storks, spoonbills and avocets. Spring and autumn are best for birds; in summer, come early or late in the day. The A22 motorway makes the journey easy.
