The story
As you stand here, high above the Atlantic on the cliffs of Porto de Mós, the first thing everyone asks is about that name. Porto de Mós translates to the Port of Millstones. If you look closely at the rugged terrain and the composition of these golden cliffs, you are looking at the very material that once powered the region’s bakeries.
For centuries, laborers quarried hard stone from these outcrops to create the heavy, circular stones used in windmills across the Algarve. This wasn't just a scenic vista; it was a vital industrial hub where the Earth was literally carved away to help feed the Portuguese population. The second question I always get is, just how high are we?
You are currently standing on some of the highest ground in the Lagos area. If you look to your right, the peak you see is Atalaia. It sits about one hundred meters above sea level.
In the sixteenth century, this was the site of a crucial watchtower. Lookouts would spend their days scanning the horizon, not for the white-sailed yachts we see today, but for the daunting sails of Barbary pirates. If a threat was spotted, they would light signal fires to alert the fortresses in Lagos.
Today, the Atalaia serves as a landmark for hikers, marking the beginning of the stunning coastal trail that winds its way along the cliff edge all the way to the famous lighthouse at Ponta da Piedade. Guests often point toward the hazy horizon and ask if they can see all the way to America. Not quite, but on a clear day, your gaze stretches past the lighthouse and all the way toward the dark, jagged silhouette of Sagres and Cape Saint Vincent.
That is the southwesternmost point of Europe, a place once believed by ancient mariners to be the literal end of the inhabited world. Then there is the geology. Why are the rocks so incredibly yellow?
These are Miocene limestone cliffs, roughly twenty million years old. If you were to walk the lower paths after a heavy rain, you might even spot the fossilized remains of ancient sea urchins and scallops embedded in the stone. The intense gold color comes from the iron oxide in the rock, which catches the light and glows like fire during the golden hour just before sunset.
Take a deep breath of that salty air, look out over the millstone cliffs, and remember that you are standing on twenty million years of history.
