History
Today’s Arroios civil parish was formed by combining the former parishes of Anjos, Pena and São Jorge de Arroios. Its territory developed in a valley descending from Areeiro towards Baixa, a natural passage that shaped movement and urban growth. Before the avenue, travel between the then-rural outskirts and the centre followed streets such as Rua da Palma, Rua Direita dos Anjos and Rua Direita de Arroios.
Water helps explain the area’s early settlement: watercourses and fertile land supported agriculture and drew residents. Igreja dos Anjos, whose parish was created in 1563, and Convento de Santana, founded in the 16th century, were among the early focal points. After the 1755 earthquake, the area received people displaced from central Lisbon, including in temporary housing between Bemposta and Arroios. Palaces, convents and, later, healthcare facilities strengthened its urban and care-giving role.
Expansion beginning in the late 19th century changed the area’s scale. The axis was first Avenida dos Anjos, then Avenida Rainha Dona Amélia and, from 1910, Avenida Almirante Reis, named for Cândido dos Reis. Its construction urbanised former estates and rural land, giving rise to neighbourhoods including Andrade, Inglaterra, Açores and the historic Bairro das Colónias, now Bairro das Novas Nações. Their streets retain thematic naming patterns, while communities of varied origins continue to add new layers to parish life.
