Roughly 40 minutes west of Lisbon is Cabo da Roca, a rocky outcrop that forms the westernmost part of mainland Europe. (Ireland is conveniently not counted in this context, being considered an island.)
Somewhat reminiscent of Peggy’s Cove in Canada, the only signs of humans at Cabo da Roca are a lighthouse, a gift shop café, some stone monuments and a hundred or so fellow visitors.
