Porto.

This formal square links Porto's older lower town with Avenida dos Aliados, centered on an equestrian monument to the constitutional monarch Pedro IV.

Praça da Liberdade helps make sense of central Porto's civic layout. Its open axis leads directly into Avenida dos Aliados, while the Pedro IV monument and Palácio das Cardosas preserve layers of political and architectural history within a busy urban crossroads.

The south side of the square preserves Palácio das Cardosas, whose Neoclassical façade began as part of a convent built after 1788. It is the oldest surviving building around the square and has dominated this edge for more than two centuries. In 1866, an equestrian monument to Pedro IV by French sculptor Anatole Calmels gave the space its political focal point. The king holds the Constitution associated with the Liberal Wars, a conflict in which Porto played a decisive role. The square changed again after 1916, when municipal rebuilding opened Avenida dos Aliados to the north. That intervention turned Praça da Liberdade into the hinge between the compact older streets and Porto's broad modern civic avenue, a relationship that remains more revealing than any single façade.

• Pedro IV is shown on horseback holding the Constitution he defended during the Liberal Wars.
• Palácio das Cardosas preserves the Neoclassical front of a former religious complex on the south side.
• The square opens north into the long civic perspective of Avenida dos Aliados.

Use the square as a transition between São Bento station, Clérigos and Avenida dos Aliados.
