Oeiras persists as a subregion of the Lisbon Metropolitan Area in Portugal located along the northern portion of the Tagus River opposite of Almada. The municipality is the primary economic hotspot of the country boasting the highest GDP due to steady employment rates and an unprecedented involvement in higher education. Its industrial importance is matched by its tourist interests including historical sights and opportunities for leisure.
Things to do in Oeiras are centralised around the waterfront, highlighted by the marina and Torre beach as well as parks and green spaces including Oeiras Municipal Park and Poets' Park. The two reigning historical monuments are the Palace of Marquês de Pombal and Palace of the Royal Estate in Caxias. A more modern attraction is the industrial site of Fábrica da Pólvora de Barcarena.
Oeiras Railway Station is the prime hub of public transportation across the region. Many bus services run routes through the area and to the nearby city of Lisbon. Airport shuttles transport passengers between Oeiras and the Lisbon airport, situated about fifteen minutes away.
The accessibility of the Tagus River attributed to the early settlement of Oeiras in addition to its lush farmland and a mild climate. As Lisbon developed, the municipality took on the role as the base of industrial and commercial operations. It was recognised as an official city in the mid-17th century.
