There’s a nickname for the people of Porto: tripeiros. Taken literally, it means “person who eats tripe”, which may sound a little insulting. But in fact it’s a reference to the 15th century, when Porto’s inhabitants gladly gave up all their meat for sailors heading off on their conquests, leaving only tripe for the locals to eat.
Today, this selflessness still survives in the residents of Porto (even if the culinary choices have thankfully become more varied). Wander the vertiginous streets winding upwards from the banks of the River Douro and you can’t fail to notice the generosity and fine manners of the Portuenses (that’s a slightly less colloquial term for the locals).
