The station on the Blue Line opened in 1959, and its architecture was designed by Falcão e Cunha, with the plastic art created by painter Maria Keil, who later updated the work.

The station has two main atriums with slightly different treatments. In the South atrium, the tiles form non‑figurative geometric patterns, where repeated diamond modules grow into larger abstract shapes. In the North atrium, the same elements are grouped in ways that almost suggest vague figurative forms.

For passengers, this makes Praça de Espanha feel more like a subtle underground gallery than a plain transport space. The walls change as you walk, making the daily commute feel a bit more lively and artistic.

Have you passed through Praça de Espanha? Did you notice the three‑dimensional diamond effect on the tiles when you looked at the walls?
