Alameda

The Alameda metro station in Lisbon is a key hub in the Portuguese capital's metro network, connecting the Green Line and the Red Line. It sits beneath the intersection of Avenida Almirante Reis and Alameda Dom Afonso Henriques, on the border of the parishes of São Jorge de Arroios, Alto do Pina, and São Jorge de Deus. The original station for the Green Line opened on June 18, 1972, as part of the final extension of the first construction phase. The architect Dinis Gomes was responsible for the design, while Maria Keil created the artistic decoration with characteristic azulejo tiles, which are distinguished by a white background and contrasting stripes in various shades of green.

When the network was expanded in the late 1990s, particularly in the run-up to the 1998 World Exposition, the station was extensively modernized and turned into an interchange. The Green Line station, now called Alameda I, was rebuilt under the direction of Manuel Taínha, with the platforms extended and the tile art supplemented by marble paintings by Noronha da Costa. The new Red Line station, Alameda II, was designed by Manuel Taínha and Alberto Barradas. It stands out for its large platform hall, which creates open space despite the depth needed to pass beneath the Green Line.

The artistic design of the Red Line and the transfer tunnel is a particular highlight for visitors. The artist Costa Pinheiro decorated parts of the tunnel with tile motifs depicting famous Portuguese seafarers such as Henry the Navigator and Vasco da Gama. Land art artist Alberto Carneiro added sculptural installations that lend the underground space a natural touch, while the Finnish artist Juahana Bloomstedt created geometric figures in marble tones. Since 2009, Alameda has no longer been a terminus, as the Red Line continues on to São Sebastião, making the station an important transit point in the city's transportation network.
