Murais de Almada Negreiros nas Gares Marítimas

This spot is dedicated to the monumental murals that Portuguese modernist José de Almada Negreiros painted for two of Lisbon's riverside maritime stations, Alcântara and Rocha do Conde de Óbidos. You get an interactive deep-dive into the history and meaning behind these massive works, which are among the most significant examples of 20th-century Portuguese art. Entry is just €3 for the murals alone, or €5 if you want the full museum experience — and it's free with a Lisboa Card.
