Porto 1820 — Decipher the Revolutionary Manifesto

Your journey begins in Praça da Liberdade, Porto's main square, developed in the 19th century on the former Capuchin convent enclosure, demolished in 1788. It was here, in this approximately 4-hectare square surrounded by neoclassical buildings and bordered by Avenida dos Aliados, that the liberal gatherings of August 24, 1820, marked the beginning of the Portuguese Liberal Revolution. As João Fernandes Campos Café, you feel the fervor rising among the crowd that already thronged here, before the manifesto's proclamation. The city hall, Câmara Municipal do Porto, stands above the square, a symbolic seat of the struggles for constitutional freedom.

Heading towards Praça da Batalha, 500 meters from Praça da Liberdade, you traverse a major historical site. This square was a place of intense popular gatherings during the 1820 liberal revolution, once hosting the Teatro de Baixo created in 1798. It was here that liberal protesters, like the Conde de Vila Real, opposed absolutism in August 1820, making Praça da Batalha an epicenter of protest in the city of Porto. The current 19th-century buildings bear witness to this urban transformation, while still echoing the revolutionary voices.

Your path then leads you to Jardim de São Lázaro, a public garden created in 1835 on the former medieval Jewish cemetery (14th century), 600 meters from Praça da Liberdade. Although its creation was later, this 2-hectare garden, with its 19th-century statues and fountains, was a strategic resting place for walkers and conspirators who traversed Porto's central district during the 1820 events. Nearby, the Teatro Nacional São João, inaugurated in 1920 on the site of the 18th-century Convento de São João Evangelista, represents a cultural venue that, even in 1820, could have served as a discreet rallying point.

Rua de Santa Catarina, a 1.5 km long pedestrian shopping street opened in 1889, shows you the dynamism of Porto's historic center. In 1820, long before it became Europe's first pedestrian street, it was already a daily thoroughfare for Portuenses attending liberal assemblies. The Art Nouveau arcades that line it today succeed the buildings seen by the insurgents. You then head towards the Reitoria da Universidade do Porto, a baroque building from 1761-1770, a former episcopal palace and seat of the University of Porto's rectorate since 1911. This site, classified as a national monument in 1929, was a hotbed of liberal debates in 1820, where figures like Pedro IV of Portugal could have found echoes for their ideas.

As you complete your thematic circuit in the Porto-et-Nord region, you have traversed the places that forged the identity of Porto and modern Portugal. From the nerve center of Praça da Liberdade to the intellectual debate sites of the University, this interactive tour has immersed you in a key moment of Portuguese heritage. You leave with an understanding of the stakes of the Portuguese Liberal Revolution of 1820, having deciphered messages and felt the spirit of a city “Antiga, Mui Nobre, Sempre Leal e Invicta” that knew how to defend its freedom. This route reveals the history of Porto, a UNESCO World Heritage site since 1996, through the eyes of those who lived it.
