Harvest time in the upper Duoro valley

Port wine has been produced and swilled here for nearly two millennia, and in 2001 UNESCO toasted the region's introduction to the World Heritage list.

The sun dips behind Cabo de Sao Vincent - Europe's most southwestern point

Dramatically situated on Europe's barren southwesternmost corner on perilous cliffs with epic Atlantic winds whipping through, its no wonder the Portuguese once believed Sagres marked the end of the earth.

This is the world's largest collection of open-air Palaeolithic art (10,000 to 40,000-years-old). And to think it all nearly disappeared under water.

This stretch of valley peppered with 17 kilometres-worth of rock engravings was only rediscovered in the late '80s when government surveyors began scoping out the area for a potential hydroelectric dam. When salivating archaeologists got wind of the Stone Age discovery, a fierce battle ensued to save the valley.
