Key Vocabulary
Dolmen (DOLE-men) — A type of prehistoric tomb typically consisting of upright stones supporting a large flat capstone; the Soto Dolmen is a refined and elongated variation of this structure.
Equinox (EE-kwuh-noks) — The two times each year when day and night are of equal length; sunlight enters the Soto Dolmen directly during these events.
Solar Alignment (SOH-lar uh-LINE-ment) — The precise positioning of a structure in relation to the sun’s path; seen in the Soto Dolmen's alignment with the spring and autumn equinoxes.
Megalithic (meg-uh-LITH-ik) — Describing large stone structures from prehistoric times; the Soto Dolmen is a prime example of megalithic engineering.
Symbolic Carvings (sim-BAH-lik KAR-vings) — Etched designs that hold spiritual or astronomical meaning; the Dolmen features spirals, solar wheels, zigzags, and figures.
Narrative Core (Based on the PSF – relabeled)
Open – JC hooks the audience by revealing a hidden prehistoric structure older than Stonehenge and more refined than Egyptian pyramids.
Info – He describes the dolmen’s location, form, and the time it was built (~3000 BCE).

Interesting Things with JC #1352: "The Soto Dolmen in Trigueros, Spain" – A sunlit corridor. A tomb from 3000 BCE. And carvings that speak of a lost civilization’s grasp of time, death, and the stars.
Transcript
Just outside Trigueros (tree-GEH-ros), in southwestern Spain, there's something older than Stonehenge and more technically refined than many Egyptian pyramids. It's not on a hilltop or behind glass—it’s under a long, unassuming earthen mound, nearly 200 feet (about 60 meters) long. Most people drive past it without knowing what’s underneath.
It’s called the Dolmen of Soto.
Now, a dolmen usually means a few upright stones topped with a flat capstone—basic prehistoric burial architecture. But the Soto dolmen is different. Built around 3000 BCE, it stretches roughly 70 feet (21 meters) into the ground. The corridor leads deep into a central chamber, lined with massive sandstone slabs. But what makes this place stand out isn’t just its size—it’s what’s carved into those stones.
Etched into the slabs are dozens of symbols—spirals, solar wheels, zigzags, and what seem to be figures or ceremonial tools. One shows a long staff or scepter. These weren’t casually scratched in. They were carved with flint tools, which means each mark could’ve taken hours—sometimes days—to create. And they weren’t random decorations. They likely carried meaning... spiritual, astronomical, or both.
Because once a year—at the spring and autumn equinoxes—the rising sun lines up perfectly with the entrance. A shaft of sunlight travels straight down the passage and hits the innermost chamber. That means this wasn’t just a tomb—it was a solar calendar. A ceremony in stone.
The people who built it had no written language, no metal tools, no pulleys. And yet they managed to quarry, shape, and position stones weighing several tons—and align them precisely with the solar year. That took astronomical knowledge, planning, and generations of passed-down know-how.
When the dolmen was rediscovered in 1923 by a landowner named Armando de Soto, it had been buried for thousands of years. Inside, archaeologists found human remains along with pottery, flint arrowheads, and stone tools—offerings for the dead. A glimpse into a belief system where death wasn’t the end, but part of a cycle timed with the movement of the sun.
Today, the site is protected, but still open to visitors. The original stones remain, along with the carvings that speak—wordlessly—of a civilization that watched the skies, honored its dead, and understood more about time and light than we usually credit them for.
These are interesting things, with JC.

Show Notes
In this episode, JC explores the Soto Dolmen in Trigueros, Spain—a 5,000-year-old megalithic tomb and solar observatory that predates Stonehenge and many pyramids. Listeners learn how ancient builders created a precise solar-aligned burial structure without metal tools or written records, using only flint and stone. The dolmen’s carvings, placement, and rediscovery in 1923 all provide a glimpse into a prehistoric belief system centered on death, astronomy, and timekeeping. This episode invites learners to rethink what ancient people knew about light, time, and engineering—making it a powerful topic for classrooms exploring ancient technology, cosmology, and cultural continuity.
