Pátra

As of the 2021 census, the municipality of Patras has a population of 215,922, while the urban population is 173,600. The core settlement has a history spanning four millennia. In the Roman period, it had become a cosmopolitan centre of the eastern Mediterranean whilst, according to the Christian tradition, it was also the place of Saint Andrew's martyrdom.

Dubbed as Greece's "Gate to the West", Patras is a commercial hub, while its busy port is a nodal point for trade and communication with Italy and the rest of Western Europe. The city has three public universities, hosting a large student population and rendering Patras an important scientific centre with a field of excellence in technological education. The Rio-Antirrio Bridge connects Patras's easternmost suburb of Rio to the town of Antirrio, connecting the Peloponnese peninsula with mainland Greece.

Every year, in February, the city hosts one of Europe's largest carnivals. Notable features of the Patras Carnival include its mammoth satirical floats and balls and parades, enjoyed by hundreds of thousands of visitors in a Mediterranean climate.
