A port for 2,000 years
People have lived where Porto stands for a very long time. Long ago, traders had a settlement there. Later, the town built stone walls around itself.
UNESCO says digs have shown that people lived at the mouth of the Douro River by the 8th century BC, when there was a Phoenician trading settlement there. The Romans called the place Portus, 'port'. In the 14th century, the town built stone walls around its medieval center and its harbor area; they were completed in 1376.
Universalis says the future kingdom of Portugal began to take shape around Porto, then called Portucale.
UNESCO: archaeological excavations show human occupation at the mouth of the Douro since the 8th century BC (a Phoenician trading settlement); the Romans named it Portus in the 1st century BC; by the 5th century an important administrative and trading center; in the 14th century massive stone walls were built around the two urban cores, the medieval town and the harbor area, completed in 1376; the historic center keeps much of its medieval street plan. Universalis: the future kingdom of Portugal began to organize around Porto (Portucale); from the 18th century the city organized the making and export of the Douro valley's wines, carried down the river by boat to its port; around the same time a steady emigration to Brazil began; two of its bridges and the Crystal Palace mark the beginnings of metal architecture.

River, bridges and sea
A river called the Douro runs past Porto to the sea. Bridges cross the river's deep valley.
Universalis says Porto sits on the edge of a plateau above the deep valley of the Douro River, which bridges cross. The city's urban area reaches the Atlantic coast, where the port of Leixões lies near Matosinhos.
The Luiz I Bridge, which Wikidata says opened in 1886, is part of Porto's World Heritage site. Across the river, on the south bank, lies Vila Nova de Gaia.
Universalis: a few kilometers from the Atlantic, on the rim of the plateau that overlooks the deep cut of the Douro valley, crossed by three bridges (as the article describes it); the urban area extends to the sea (residential districts of Foz; the port of Leixões, near Matosinhos) and to the south bank (Vila Nova de Gaia).
