Events in Castro Marim

Main places

• Castelo de Castro Marim

  Medieval castle on top of the village, first headquarters of the Order of Christ (1319–1357) by papal bull from John XXII at King Dinis's request, before it moved to Tomar. Reinforced by King Manuel I in 1509 against Muslim piracy. Today the main stage of the Dias Medievais fair, with a combined ticket with the Fort of São Sebastião.

• Forte de São Sebastião

  Bastion-style fort started in 1641 by King João IV during the Restoration War with Spain — turning Castro Marim into the Algarve's main military post. Five irregular bastions adapted to the terrain, main gate facing north. Classified a National Monument. A 5-min walk from the Castle.

• Castro Marim Old Town

  Whitewashed village on the slope between the Castle and the Fort of São Sebastião, with narrow streets, single-storey houses and the Igreja Matriz de Nossa Senhora dos Mártires. Original royal charter from 1277 (King Afonso III), renewed in 1504 (King Manuel I). Direct view over the Guadiana estuary and Spain on the other side.

• Sapal Nature Reserve

  Mainland Portugal's first nature reserve, created in 1975. 2,300 ha of salt marsh, salt pans and channels between Castro Marim and Vila Real de Santo António, at the mouth of the Guadiana. 153 bird species, with flamingos nesting locally from 2020 (550 chicks). The black-winged stilt is the reserve's symbol. Visitor centre open to the public.

• Salt pans + Flor de Sal DOP

  Traditional hand-harvested sea salt and flor de sal — protected as 'Sal de Castro Marim / Flor de Sal de Castro Marim' DOP; the earliest written mention is in the 1277 royal charter. Flor de sal forms on the surface of the crystallisation pools when the water reaches saturation. Guided visits at Salmarim, Terras de Sal and Jara Domingues, mostly between June and September.

• Praia de Altura

  The council's only ocean beach, in Altura parish — long stretch of sand connecting east to Manta Rota and Monte Gordo, with calmer and warmer water than the rest of the Algarve. Beach service, restaurants and a cycle path through to Vila Real de Santo António. Blue Flag.

• Odeleite Reservoir ('blue river')

  Reservoir on the Odeleite River, in the inland part of the council, known for its blue dragon-shaped curves seen from above — viral on social media. Reached on foot or by bike from Odeleite village. Good area for canoeing, kayaking and SUP.

• Azinhal and Odeleite (the inland)

  The rural parishes to the north, in the barrocal and the transition to the Caldeirão hills. Whitewashed single-pitch houses, stepped streets, black goats, and the Spanish border on the Guadiana. A classic stop on inland-east Algarve road-trips.
