The Street That Remembers a Siege
Before we go inside, I need to tell you why this street is called Rua do Heroísmo, because it's not just a nice name someone picked.
Between July 1832 and August 1833, Porto was under siege for 14 months. This was the Liberal Wars, and it was a civil war. Dom Pedro, the liberal, held Porto. Dom Miguel, the absolutist, surrounded it. Two brothers fighting over Portugal's political soul: constitutional monarchy versus absolute royal power.
Porto chose the liberal side, which meant the city endured over a year of isolation, bombardment, and near-starvation. The population suffered tremendously, but the city refused to surrender. That resistance became symbolic of the entire liberal cause across Portugal.
The street's name comes from one particular day: September 29, 1832. That morning, Miguelists managed to break through Porto's eastern defenses right here, in this neighborhood. What followed was nine hours of brutal street-by-street fighting. Houses became fortifications. Civilians got caught in crossfire. When the attackers finally withdrew at nightfall, over 650 casualties marked the day.
They named this street Rua do Heroísmo to honor not just that battle, but the entire 14-month ordeal. It's a memorial built into the city's geography. Every time someone writes this address, they're remembering Porto's sacrifice during Portugal's defining political struggle of the 19th century.
This siege forged Porto's identity as a progressive city willing to endure hardship for principles. That self-image stuck. You'll see it in the 1891 revolution room inside, you'll see it in how this city talks about itself even today.
The building you're about to enter sits on a street named for resistance. Keep that in mind as you learn about its later history with PIDE. Porto has complicated relationships with power and freedom. This street name is where that story starts.
