Port wine was born in the upper Douro valley, and the river that meanders through the area deserves to be as famous as the city itself. The breathtaking wine-growing landscapes of the basin are veritable works of art, sculpted by the hand of Man. With its arid climate in summer and temperatures hovering around 40°C, winter is very harsh and very cold. Difficult to access, the mountainous terrain is highly unsuitable for farming. Before the dam, the Douro River was much lower and its current much slower than it is today.
