Arroios is a station on the Green Line of the Lisbon Metro. The station is located in the Almirante Reis Avenue, in Arroios neighbourhood.
The station, which opened on 18 June 1972, was designed by the architect Denis Gomes with art installations by the painter Maria Keil.[1]
On 19 July 2017, the station was closed for extensive renovations; the station's platforms only had room for 4 cars, requiring use of selective door operation.[2] The platforms were expanded from 75 to 105 metres, enabling all stations on the Green Line to be able to support six-car trains.[3] The station reopened on 14 September 2021.[4]
