The history of Porto

Assembled from 4 dug tiles · 72 sourced records · 499 BC–2015 · last reviewed 11 October 2026

Porto grew from Cale, a settlement known from around the fifth century BC, into a walled medieval city and then a capital of commerce and revolution. Across its squares and streets, monks, kings, crusaders and city planners each left their mark, from a sixth-century diocese to a nineteenth-century avenue.

These are the individual spots Strata has dug in Porto — not a guide to the town, but a record of what happened on particular ground.

Questions about Porto

What is Porto known for historically?
Porto is known for its layered public spaces built over centuries of change: Liberdade Square, laid out from 1718 as Praça Nova; Terreiro da Sé, cleared of a medieval neighbourhood in the 1930s and 1940s; and Rua de Cedofeita, opened in 1762 under João de Almada e Melo's renewal plan. The city's name traces to Cale, the settlement recorded here from around 499 BC, later Portus Cale under Roman rule.
What happened at Praça da Liberdade in Porto?
Praça da Liberdade began as Praça Nova in 1718, when the Cathedral chapter surrendered land outside the city walls. It later witnessed political hangings in 1829, a republic proclaimed from the city hall balcony on 31 January 1891, and the rise of Avenida dos Aliados in 1916 after a whole neighbourhood was cleared. A bronze equestrian monument to Dom Pedro IV, cast in Belgium, was unveiled there on 19 October 1866.
What happened at the cathedral square, Terreiro da Sé, in Porto?
Terreiro da Sé was created in the 1930s and 1940s when planners demolished the medieval quarter pressed against the cathedral, removing streets, a bishop's jail and a chapel. The ground had served as a burial site since the ninth century and as a gathering point for crusaders in 1147 before they helped take Lisbon.
What is the history of Rua de Cedofeita in Porto?
Rua de Cedofeita was opened in 1762 as part of a renewal plan led by João de Almada e Melo, taking its name from the nearby Church of São Martinho de Cedofeita. Its row houses, mostly filled in after 1839, were designated a protected Immovable Cultural Heritage ensemble in 1993.
What happened at Praça de Carlos Alberto in Porto?
Praça de Carlos Alberto occupies ground once part of the parish of Vitória, founded in 1583 and dissolved in 2013, near the former Judiaria do Olival, Porto's largest Jewish quarter, expelled at the end of the fifteenth century. The square was once a farriers' yard at a city gate, and a hospital for the Third Order of Carmel broke ground there in 1791.
Who is commemorated by the bronze monument in Praça da Liberdade?
The monument depicts Dom Pedro IV on horseback, holding the constitution he fought for, cast in bronze in Belgium and raised on a ten-metre column of lioz stone. It was unveiled on 19 October 1866, replacing a provisional pedestal first erected in 1852.
