The story
As you walk along this broad, tree-lined avenue, you might notice how the air feels a bit more open here than in the narrow, winding alleys of the old city. This is the heart of the Avenidas Novas, the New Avenues, a grand expansion that pushed Lisbon northward at the turn of the twentieth century. You are currently treading on a path that connects the circular pulse of Marquês de Pombal with the gardens of Praça de Espanha, and the name on the signs—António Augusto de Aguiar—belongs to a man who lived exactly at the intersection of cold science and warm, red wine.
António Augusto de Aguiar was born in Lisbon in 1838. He was not a soldier or a king, but a chemist with a brilliant, restless mind. He spent his days at the Polytechnic School, where he was such an engaging professor that his students were known to break into spontaneous applause at the end of his lectures—a rare sight in the formal classrooms of the 1800s. Even the Emperor of Brazil, Dom Pedro II, once made a point of visiting Lisbon just to sit in on one of Aguiar’s chemistry lessons.
But Aguiar didn’t just stay in the lab. He was a man who believed science should serve the people. When the Portuguese wine industry was struggling, he used his knowledge of enology to help modernize and save the country’s most famous export. Later, he stepped into the world of politics, serving as the Minister of Public Works and Industry between 1883 and 1885. He was a visionary who helped plan the very modernization of the city you are walking through now.
When he died in 1887 at only forty-nine years old, Lisbon felt the loss of a true public servant. This avenue was planned in 1899 to honor his legacy. Today, the street is a fascinating blend of different eras. To your side, you will see the massive glass and stone facade of El Corte Inglés, a modern temple of commerce. Yet, if you look closer at the older buildings nearby, you might spot the elegant, symmetrical lines of Art Deco architecture from the 1930s. At numbers 173 to 177, for instance, there is a building decorated with two large, mysterious female masks wearing crowns of flowers.
The avenue serves as a bridge, not just between two squares, but between the nineteenth-century dream of a scientific future and the busy reality of modern Lisbon. As you continue your walk, take a moment to look at the ground. Notice the traditional Portuguese pavement beneath your feet, the calcada. Look for a spot where the white and black stones form a sharp, clean pattern. It is a small, geometric reminder of the order and beauty that a scientist like Aguiar would have appreciated.
