It’s older than Stonehenge. Seriously. While the famous circles in Wiltshire were getting started around 2500 BCE, the Cromeleque dos Almendres had already been standing for two millennia. You drive about 15 kilometers west of Évora, past the cork oak forests and the dust of the Alentejo backroads, and suddenly, there they are. 95 monoliths. They aren’t jagged or sharp; they’re rounded, granite eggs that look like they’ve grown out of the earth itself.
Most people call it the "Portuguese Stonehenge," but that’s honestly a bit of a lazy comparison. It’s its own beast entirely.
You’ve probably seen photos, but they don't capture the scale. This isn't just one ring. It's two distinct enclosures, built at different times, over thousands of years. It’s a mess of history. It’s Neolithic. It’s Chalcolithic. It’s a place where the sun, the moon, and the stars were tracked by people who didn't have writing but had an incredible grasp of geometry.
The Accidental Discovery of a Masterpiece
Believe it or not, this place was "lost" until 1964. Henrique Leonor Pina, an investigator working on the Geological Map of Portugal, stumbled upon it while doing fieldwork. Imagine that. One of the most significant megalithic sites in Europe, and it was basically just a bunch of rocks hidden in a private estate for centuries.
When Pina found it, many of the stones were fallen or buried. The restoration process in the late 60s and early 70s was a massive undertaking, but it stayed relatively quiet for decades. Even now, despite the rise of tourism in the Alentejo region, it feels rugged. There’s no massive visitor center with a gift shop selling plastic druid hats. It’s just you, the wind, and these ancient, silent witnesses.
The Cromeleque dos Almendres wasn't built in a weekend. It evolved.
The smaller, circular enclosure to the east is the oldest, dating back to the Early Neolithic (around the 6th millennium BCE). The larger, oval-shaped enclosure to the west came later, during the Middle Neolithic. By the Late Neolithic, the whole thing was modified. Some stones were moved. Some were engraved. It shows that these people didn't just build a monument and leave; they stayed. They iterated. They cared about this specific patch of hillside for thousands of years.
Reading the Stones: Art and Archaeoastronomy
If you look closely at stone number 56, you’ll see it. It’s a series of sunken circles, often called "cupmarks." Some people think they’re maps of constellations. Others think they were for ritual offerings. Honestly? Nobody knows for sure.

There’s also stone 57, which features thirteen carved "crooks" or staffs. These symbols appear in megalithic art all across the Atlantic facade, from Brittany to Iberia. Archaeologists like Philine Kalb have spent years trying to decode what these signify. Power? Agriculture? Shepherding? It’s probably a mix of all three.
The alignment is what really gets people, though.
- The main axis of the enclosures is aligned with the equinoxes.
- On the morning of the winter solstice, the sun rises in a direct line with the Menhir of Almendres, which sits about a kilometer away.
It’s a massive, granite calendar. They were tracking the seasons to survive, sure, but there’s a sense of theater to it. These stones were placed to create a specific visual experience at specific times of the year. It’s prehistoric cinema.
The Problem with "Restoration"
Here is something the brochures don't always tell you: the site we see today is a reconstruction.
When Pina found the site, many stones were toppled. In the 1960s, archaeologists stood them back up. They used the holes in the ground and the lean of the earth to figure out where they went. For the most part, they got it right. But there is a lingering debate in the archaeological community about whether every single stone is exactly where it was 7,000 years ago.
Does it matter? To a purist, maybe. But when you stand in the center of the oval and look toward the horizon, the intentionality of the layout is undeniable. The stones are graded in height, with the taller ones positioned to frame the sunrise. Even if a few are inches off their original mark, the "soul" of the site remains intact.
Why Almendres Matters in 2026
We live in a world of planned obsolescence. Your phone will be junk in three years. Your car might last fifteen. The Cromeleque dos Almendres has lasted seven thousand.

It’s a reminder that the Alentejo wasn't some backwater. It was a hub. The "Megalithic Universe" of Évora includes over 10 monuments within a short drive, like the Great Dolmen of Zambujeiro. This was a sacred landscape. People traveled distances to be here.
Walking through the stones today, you notice the texture. The granite is covered in lichen—shades of neon orange, pale green, and ghostly white. It’s alive.
The site isn't fenced off like Stonehenge. You can walk among the stones. You can touch the granite (though, honestly, please be gentle; skin oils aren't great for 7,000-year-old rock). This accessibility is its greatest strength and its biggest threat. As more people discover the Alentejo, the pressure on the site grows. There are no guards. There are no ropes. It relies on the respect of the visitor.
Planning a Visit: What to Actually Do
Don't just drive up, take a selfie, and leave. That’s a waste.
First, go to the Menhir of Almendres first. It’s a single, massive stone standing alone in a field nearby. It acts as a gateway or a pointer to the main cromlech. Most people skip it because it's a bit of a walk, but it provides the necessary context for the "solar gate" effect.
Second, time your visit for the "Golden Hour." The Alentejo sun is brutal at midday. The granite gets washed out. But in the hour before sunset? The shadows stretch. The carvings on the stones—the dimples and the lines—suddenly become visible in the raking light. It's haunting.
Third, check out the Centro de Interpretação Ambiental e Cultural de Guadalupe. It’s a small center in the nearby village. It’s not flashy, but it explains the geology and the flora of the region. Knowing that these stones were hauled from nearby outcrops using nothing but wooden rollers and sheer human will makes the site much more impressive.

The Technical Reality of the Site
The stones are mostly porphyritic granite.
They weren't just picked up off the ground. They were shaped. You can see the pecking marks where ancient tools were used to round off the edges. The largest stones weigh several tons.
Geographically, the site sits on a gentle slope facing east. This wasn't an accident. By placing the monument on a slope rather than a flat plain, the builders created a tiered effect. When you stand at the top of the hill, you can see over the tops of the lower stones toward the horizon. It’s sophisticated landscape architecture.
Common Misconceptions
People love to talk about "energy ley lines" and "alien intervention." Let’s be real: there’s no evidence for that. What there is evidence for is a highly organized, deeply spiritual society that understood the cycles of the earth better than most of us do today.
Another mistake is thinking this was a burial ground. While some megalithic sites (like dolmens) were definitely tombs, the Cromeleque dos Almendres appears to have been a place of gathering. A temple? A courthouse? A social hub? Probably all of the above. It was a place where the community reaffirmed its connection to the cosmos.
Actionable Steps for the Curious Traveler
If you’re heading to the Alentejo, do it right.
- Stay in Évora. It’s a UNESCO World Heritage city and makes the perfect base. You can get to the stones in 20 minutes by car.
- Rent a sturdy car. The road to the site is unpaved and can be pretty washboard-y and dusty. A tiny rental might struggle if it’s been raining.
- Bring a flashlight. If you stay for sunset, the walk back to the parking area is pitch black.
- Visit the museum. The Museu de Évora holds many of the smaller artifacts found during the excavations of the surrounding megaliths. It fills in the gaps.
- Look for the "Eye" idols. Small limestone cylinders with "owl eyes" were often found in these areas. They represent a deity or an ancestor. Seeing them in the museum makes the stones feel less like abstract shapes and more like representations of beings.
The Cromeleque dos Almendres doesn't need a gift shop or a light show to be impressive. Its power lies in its silence and its survival. It has seen empires rise and fall, the climate change, and the world transform. And yet, the stones still point to the same spot on the horizon where the sun rises every spring. There’s something deeply comforting about that.
The site is currently free to enter, though there have been talks about implementing a small fee to help with conservation. Go now while it still feels like a secret discovery. Walk the perimeter, find the engravings on stone 56, and just sit for a minute. You’re sitting in a spot where humans have gathered for 8,000 years. That’s worth the drive.
