Porto (PT)
Porto , also known as Oporto in English, is the second-largest city in Portugal, after Lisbon, and one of the major urban areas in Southwestern Europe. Located along the Douro river estuary in Northern Portugal, Porto is one of the oldest European centres, and its historical core was proclaimed a World Heritage Site by UNESCO in 1996. Its settlement dates back many centuries, when it was an outpost of the Roman Empire. Its Latin name, Portus Cale, has been referred to as the origin of the name "Portugal", based on transliteration and oral evolution from Latin. In Portuguese the name of the city is spelled with a definite article ("o Porto"; English: the port). Consequently, its English name evolved from a misinterpretation of the oral pronunciation and referred to as Oporto in modern literature and by many speakers.
