Oeiras (Portuguese pronunciation: [o'?j]) is a municipality in western part of the Lisbon Metropolitan Area, subregion of Greater Lisbon, in continental Portugal. It is part of the urban agglomeration of Lisbon. The population in 2011 was 172,120, in an area of 45.88 km², making the municipality the fifth-most densely populated in Portugal.
Oeiras is an important economic hub, being one of the most highly developed municipalities of Portugal and Europe. It has the highest GDP Per Capita in the country, being also the second municipality (right after Lisbon) with the highest purchasing power as well as the second one collecting taxes in the country. This economic results are also a reflection of the inhabitants studies, being Oeiras the municipality with the highest concentration of population with higher education in the country and the lowest unemployment rate in the Lisbon area.
The mild climate, access to water, quality of its soils and geographically privileged location at the mouth of the Tagus River attracted early settlement to this region. The rugged hilltops of the interior conditioned cultivation and allowed the settlement of several small agricultural castros within the regions limits, such as Castro of Leceia (which was classified in 1963 as a property of public interest). This archaeological site is a witness to the early settlements and defensive structures that developed during the Calcolithic period, although Paleolithic camps, such as Gruta da Ponte da Laje suggest earlier settlements.
Remnants of the Roman occupation of the Iberian peninsula are evident in many places throughout the municipality, including mosaics, specifically along the Rua das Alcássimas, and a Roman bridge. The latter Arab conquest left behind several toponomic markers, such as Arab/Moorish place names: Alcássimas, Algés, Alpendroado and Quinta da Moura.
The settlement of Oeiras dates back to 1208, when the area was colonized by Christian tribes from the northern Portugal, moving south into warmer agricultural lands.
At the beginning of the Age of Discoveries, Oeiras became the industrial and commercial warehouse of Lisbon. The development of the Gunpowder factory (Portuguese: Fábrica da Pólvora) in Barcarena, was therefore, important in the expansion of the Portuguese dominions of the Orient, in addition to the aggregate extraction and calcium oxide furnaces in Paço de Arcos. These industries were supported and guarded by the construction of several fortifications along a defensive maritime line that ringed the southern coast to Lisbon and that controlled navigation in the Tagus estuary, from the 16th to 18th centuries. This perimeter included the Fort of São Lourenço da Cabeça Seca (also known as the Lighthouse or Tower of Bugio), rising from a tiny islet in the middle of the Tagus River, and the Fort of São Julião da Barra, both examples of the Renaissance military architecture.
The municipality was founded in 1759 by the Marquis of Pombal, as a reward by King Joseph I to his minister for his efforts in rebuilding the Lisbon historical downtown (Portuguese: Baixa) after the 1755 Lisbon earthquake. A royal charter, dated 7 June 1759, gave jurisdiction of the lands within Oeiras to the King's loyal minister, becoming the first Count of Oeiras. A month later the small village was elevated to the status of town, and then municipal status on 13 June 1759. Although Oeiras had a history of settlement, it was during the reign of Joseph I, that economic and social development, conditioned by the influence of the King's Minister, who promoted innovation and supported local economic activities.
In 1770, the first agricultural and industrial fair was established in Oeiras, representing a unique national event, that also contributed to the creation of fishing shelters, a new customhouse and factory, among other projects. One of the principal developments was the construction of the estate of the Marquess of Pombal, that today exists in its original form, with garden, palace and agricultural dependencies, such as the wine cellar, barn and other buildings, today housing the national institutions responsible for bio-science.
In 1894, the municipality was extinguished, but reestablished four years later on 13 January 1898. It was reconstituted without Carcavelos, which was annexed to Cascais, while gaining the civil parish of Benfica. Between 17th and 18th century several estates and palaces began to be constructed, in order to explore agricultural production, principally cereals and vineyards, that supported the growing markets of Lisbon. But, this activity began to decline by the 19th century, and was replaced by new industry, supported by the Lisbon-Cascais railway link, first inaugurated in 1889. Large factories began to locate in the municipality, among them the Fábrica do Papel, the Fundição de Oeiras, a Lusalite and Fermentos Holandeses.
At the same time, between the 19th and 20th century, the growth of leisure activities along the coast transformed Oeiras, which became a privileged location for the Portuguese elite. By the beginning of the 20th century, many of the beaches in Oeiras were already occupied by the higher social classes, who travelled to the municipality for medical reasons (believing the air and beach-waters were medicinal). The construction of the national roadway 6 (EN6) would later link Lisboa to Cascais, permitting new travellers to experience the zone, resulting in an influx of new residents that expanded the urban centres, giving rise to beach "chalets" and summer cottages. Simultaneously, the concentration of economic activities in Lisbon, and surrounding urban municipalities, meant that Oeiras had direct access to the capital.
After 1940-50 the municipality began to function as a suburb and bedroom community, attracting more residential growth along the coast. This culminated in the 1970s, with the appearance of illegal urban settlements, squatters and barrios. Until the 1980s, the municipality was dependent on the much larger urban centre for development.
But, by the end of the 1980s, it began to constitute its own economic pole in the Lisbon Metropolitan Area, concentrating its development on teritary activities linked to science, investigation, information technology and communications. At the end of the 20th century the municipality became known for its high standard of living, leaving behind its image as a suburb of Lisbon, and assuming an important position as a centre associated with new technologies (with the establishment of various technology parks, such as Taguspark and LagoasPark) and service industries. The elevated standard of living and work allowed the region to obtain several awards, including the "Melhor Concelho para Trabalhar" (Best Municipality to Work), "Município de excelência" (Municipal Excellency Award), "European Enterprise Award" and the "ECOXXI" Award.
The municipality is located along the northern margin and mouth of the Tagus River, across from the municipality of Almada, surrounded by the municipalities of Lisbon (east), Sintra (north), Amadora (northeast) and Cascais (west).
Along the 10 km coastline, where the Tagus River meets the ocean, several natural coves were in the origin of its beaches:
Two major green areas spread over Oeiras municipality: the Estação Agronómica Nacional and the Jamor sports complex.
Oeiras municipality had a population of 172,120 as of the 2011 Census, retaining the nation's 11th most-populous municipality and the 5th in terms of population density.
The major expansion in the municipalities demographics, much like the other municipalities that circle Lisbon, occurred in the second half of the 20th century. Realizing this growth, and understanding that there was a need to control urban sprawl, in 1948 the Plano de Urbanização da Costa do Sol (Sun Coast Urbanization Plan) was adopted to manage this activities in the northern margin of the Tagus. This remained active until 1994, when the first Plano Director Municipal (Municipal Plan) was adopted.
Demographically, the population is divided into 52.6% women to 47.4% men, with the majority of its resident population between the 25 and 64 year cohort (approximately 92,978 inhabitants). Rounding out these numbers there are 24,153 seniors over the age of 65 and 22,685 residents less than 14 years of age. Oeiras has the highest concentration of bachelors' and PhD's in the country, as well as the highest number of graduates in the country: 26%.

The industrialized and heavily commercial municipality is occupied by several facilities, that include the headquarters of SIC and TVI (two private Portuguese television networks), many large multinational and technology companies, including Nestlé, McDonald's, BP, General Electric, Cisco, Synopsys, Hewlett-Packard, and Samsung. The headquarters of NetJets Europe, Omni Aviation and the its Portuguese subsidiary airline White Airways  are also located in the area. The first Portuguese semiconductor company Chipidea was established in Oeiras until being acquired by MIPS Technologies for $147 million.
The region is also a technology and service incubator with the purposeful creation of many science, technology, research institutions and business parks, including:
Several security and both private and governmental institutions are also within the vicinity: the NATO command post (Joint Command Lisbon); IGC - Instituto Gulbenkian de Ciência, and a pole of the Instituto Nacional dos Recursos Biológicos, responsible for agrarian research, the Estação Agronómica Nacional (National Agronomy Station), are all located within the municipality.
Oeiras offers a range of points of interest, ranging from monuments of unique and historical value, such as the Palace of Marquês de Pombal and Palace of the Royal Estate in Caxias (that dates from the 18th century and surrounded by luxurious gardens) to sites with industrial history, like the Fábrica da Pólvora de Barcarena (Gunpowder Factory), a recovered arms factory used for leisure and cultural purposes.
Leisure facilities include the sports complex of Jamor, the Oeiras' promenade (linking Algés and Oeiras e São Julião da Barra) and the yacht harbour, in addition to other local parks and green-spaces. The modern Parque dos Poetas (Poets' Park), a green space with statues of Portuguese poets and writers is also one of the ex-libris of Oeiras. Many of the former town centres have been recovered, displaying monuments and tourist-oriented venues for leisure, cultural, gastronomic and social events (for example the town of Paço de Arcos).
Education have always been one of the top priorities of Oeiras.
