Serpa has its origins in early settlement that preceded the Roman occupation of the Iberian peninsula. The neighbouring town of Beja became the capital of southern Lusitanian. Serpa grew through the settlement of Roman colonists, with proof coming from various archaeological remains within the Roman villa. Moorish settlement followed this period, and remained until the Reconquista. As a result of Serpa's proximity to the Spanish border, the town has always been a defensive stronghold. In the 13th century, owing to its location on the left bank of the Guadiana, it was occupied by forces loyal to Castile. On 1281, King D. Alfonso X of Castile delimited the municipality, attributing a Foral to the town, from Seville, in order to encourage settlement and expansion. Following the Reconquista, in 1295, Serpa received a new foral from Portuguese King D. Dinis. The local keep that dominated Serpa was partly damaged as a result of the last Spanish invasion. At that time, the king ordered the re-construction of the castle, as well as the erection of a wall fortification. A new foral was issued in 1513, by King D. Manuel I, who was the former master of Serpa. During the 17th century, the walls and system of bastions were adapted to serve as a defensive line by Nicolau de Langres. On 30 January 1954, the walls of Serpa were classified as a Monumento Nacional. Following the Carnation Revolution, thePortuguese Communist Party gained strong support in the area, where it continues to be popular. On 26 August 2003, the town of Serpa was elevated to city status. Meanwhile, on 28 January 2013, the historic centre of Serpa of São Salvador and Santa Maria, was re-incorporated into a single civil parish.
Geography
Administratively, the municipality is divided into five civil parishes:
The area surrounding Serpa consists mostly of farms and cultivated lands of wheat, that have traditionally been the staple of the local economy, employing many people. Due to the area's strong agricultural reliance, the local population has traditionally been agrarian farmers and sheepherders. This has also resulted in the production of its spicy and strong-smelling cheeses, produced in the area and commercialized throughout Portugal. Slightly to the northeast, in the region of Pias, the area cultivates vineyards in order to produce local wines. On 27 April 2006, GE Energy Financial Services, PowerLight Corporation and Catavento Lda. announced that they would build one of the world's largest solar photovoltaic power projects at a single site in Serpa. The 11-megawatt solar power station, comprising 52,000 photovoltaic modules, would be built in one of Europe's sunniest areas. The power station was inaugurated on 28 March 2007.
Culture
Urban residents of Lisbon, Beja and other cities maintain country homes in Serpa, or take weekend breaks to the area as a result of Serpa's rural location and laid back lifestyle. Other local and regional specialties include Shepherd's Lamb Stew, a Clam and Pork dish and Sweet Potato Pastries.
