Cabo da Roca, the western most point of the European mainland, has inspired our travellers. The view and what it brings to mind is the perfect starting point for their voyage of exploration.
Fabian looked South, pointing towards his childhood home in South America: where many an expedition of the famous historical Portuguese explorers was headed.
And Yldau pointed North and waved towards her home town of Rotterdam, where their journey of re-discovering the “old” continent of Europe will eventually take them. Or did she? There was some debate about the right directions… perhaps an expert could help?
So, on this richly atmospheric spot our travellers met up with retired Portuguese Navy captain, Joaquim Alves Gaspar. A specialist in Navigation, Hydrographic Surveying and Mathematical Cartography, (maps, basically) he is now a researcher at the University of Lisbon and dedicates his time to solving age-old mysteries about maps and how they were used centuries ago. Joaquim had one of those old seafarers’ maps to show our travellers but advised them not to rely too much on old maps: they should find what they are aiming for in their own way!
