Álamo Roman Dam
At the edge of the hamlet of Álamo, about 11 km south of Alcoutim, stands a Roman dam. It sits in the Fornalha gully, a tributary of the Guadiana. It is a straight wall about 40 metres long, more than 8 metres high and 2.8 metres thick, built of mortared greywacke blocks laid in horizontal courses. Seven buttresses are visible on the south side. It is thought to have held around 2,100 cubic metres of water in a reservoir some 90 metres long. The archaeologist Estácio da Veiga identified and recorded it in the late 19th century, and it probably supplied the Roman villa of Álamo nearby. It has been a listed monument since 1992.

Alcoutim Castle
Alcoutim Castle was built on the orders of King Dinis around 1304, when the Guadiana became the border with Castile. It stands on a hill between the river and the Cadavais stream, and it was in this town that the Iberian kings signed the Peace of Alcoutim in 1371. From the wall walk you look out over the Guadiana to Sanlúcar on the far bank. On the north side a viewing scope points at Castelo Velho, the Islamic fort 1 km outside town. Inside is the archaeology museum, opened in 2000, with an exhibition running from the Neolithic to the 20th century. The old powder magazine holds 'Jogos Intemporais': 39 game boards carved into slabs of schist and 18 gaming pieces, all found at Castelo Velho. It is the largest set of Islamic-period games from a single archaeological site in Portugal.

Guerreiros do Rio
Guerreiros do Rio is a riverside village on the Guadiana, about 8 km south of Alcoutim. Life here has always faced the river: for part of the 20th century it was a hub for smuggling with Spain, mostly dried fruit and other foodstuffs, wine and textiles. The village is home to the Museu do Rio, a branch of Alcoutim's municipal museum. It began in 1994 with an exhibition in the old village primary school, was extended from 2003 and reopened in September 2006 with the exhibition 'Olhar o Guadiana por dentro'. It tells the river's story: navigation and ore transport, traditional fishing, smuggling and the villages along the banks. Since 2008 it has also shown 'Barcos Tradicionais do Baixo Guadiana', scale models of the boats that worked the river until the mid-1960s, built by José Murta Pereira, who was born in the village. The GR15 Rota do Guadiana trail passes through on its stretch between Álamo and Alcoutim.

Pereiro
Pereiro is a village in the north-eastern Algarve, inland within the municipality of Alcoutim, and now shares a parish with the town itself. Its parish church of São Marcos is documented from the first half of the 16th century. Inside is one of the most interesting sets of altarpieces in this corner of the Algarve, above all the altarpiece of souls, the only Mannerist example to survive in the area. The village also has the Casa do Ferreiro, a branch of Alcoutim's municipal museum that opened in 2011 in the old blacksmith's workshop, shut for more than forty years before that. It shows farm tools, household ironwork and the rings made from horseshoe nails that young men gave their sweethearts, along with a documentary of local memories. Pereiro is the start of the PR4 Caminhos da Fonte, a walk of about 10 km past the Pereiro reservoir, holm oak groves and the hamlet of Fonte Zambujo.
