The Burren, Ireland’s Most Famous Ancient Portal Stones

Delighted to have found the most famous place in the Burren!

We Got Lost Trying to Find the Burren

“Excuse me, I’m looking for the famous rock thingy in the Burren?” I asked the Irish gentleman. “You know, the one with the rocks that are like this, and this, with one like this?” I flailed my hands around, making a tipped square shape. “I think it’s called Hole of Sorrows, or something creepy like that?”

Where is the Burren in Ireland?

The man shook his head with a smile, and replied with that delightful Irish accent, “Google Maps uses that ‘Hole of Sorrows’ term, but it’s mistranslated. What you’re looking for is called the Poulnabrone dolmen. It’s a portal tomb dating back to 5,000 or 6,000 years ago. It’s really quite remarkable!”

Like so many other locals we encountered on our week in Ireland, this stranger was incredibly kind. He drew a map for us, and soon we were on our way. It was a relief to be moving again, as our traveling toddler had just thrown up all over the car during our visit to the Cliffs of Moher, and the interior was starting to smell.

Poulnabrone is a fascinating and famous heap of rocks.

The Connection Between Boston and Ireland

You may ask how I knew about these stones if I’d never been to Ireland before this trip, and why I was so keen to track them down. Well, the answer is a tad goofy. You see, my dear hometown of Boston has a massive Irish population, and names its restaurants and bars accordingly.

As a result, the entire time I was planning our Ireland trip, I kept looking up from the map and exclaiming, “Hey, there’s a bar in Kendall Square named for that town!” or, “Whoa — that place is also a restaurant in downtown Boston!”

So what about the Burren? Well, it was one of my favorite eateries in the town of Somerville, just north of Boston, where I lived for five years! What is the logo for Somerville’s Burren restaurant?

Why, you better believe it is that magical stone portal that I found myself tracking down once we finally set foot in Ireland! I wonder if countries know what good marketing they do for travel, simply by having expats use their place names for stores…

Facts About the Burren in Ireland

As we drove, I looked up what, exactly, “the Burren” was. From the Somerville restaurant, I thought it just meant that one rock formation, but in fact, the Burren is a 48-square-mile region in County Clare, Ireland with some of the most unique “limestone pavement” ground you have ever seen.

For those (like me) who enjoy rolling words around in your mouth, the term for the cracks that cover the moon-like ground of the Burren is: “Grike.” The resulting rock bulges are called “Clints.” (Excuse me while I put my mouth on my baby‘s belly and say: “Burrrren! Griiiikes! Clinnnts!” until he giggles.)

Something that surprised me was that the Burren is considered a “Karst” or “Glacio-Karst” landscape. This struck me as odd because I know and love karsts — as you may have seen from my posts about karsts in Cuba, Laos, and Vietnam — but these supposed karsts of Ireland look nothing like the tall, flat hills I’ve frolicked past around the world. If there’s a Geologist reading this, please explain why Ireland’s karsts are small bumps instead of mini-mountains.

Finding Poulnabrone on Confusing Roads

It was more confusing than expected to find Poulnabrone, especially because we kept finding ourselves on roads that GPS named, “Unnamed Road.” We passed the time making jokes with the name, singing, “Pull the Brony!” (a “Brony” being the official term for men who love My Little Ponies).

Suddenly, the moonscape of nothingness revealed a clump of people huddled around a heap of rocks. “COLIN!” I screamed, “That’s the rock thingy! Pull the car over!!!” Colin calmed me down because I was alarming the baby, then pulled into the parking lot. We bundled up and stepped out into the wind.

Ta da! One of the most famous dolmens in the world!

How Old is the Burren?

So what exactly is this Poulnabrone dolmen, besides an intriguing decoration on a pub near Boston? In fact, it is a “portal tomb” constructed in the Neolithic period, between 4200 B.C.E. and 2900 B.C.E. When it cracked and fell a few years back, archaeologists were able to dig around under it, and found twenty-two humans elaborately buried beneath!

Yes, you heard that right… the 200,000+ people who visit Poulnabrone each year in Ireland are walking right above the bones of twenty-two people from six thousand years ago.

History of Portal Stones in Ireland

There are around 174 other “portal tombs” in Ireland, and the “portal” part of the name seems to refer to the door-like shape of the structures. For me, however, the term truly stirs the imagination. What it conjures up is the image of a time warp, right?

I half expected baby, Colin, and me to be transported momentarily back to 4200 B.C.E. if we walked through the stones! (See more imaginative drawing inspiration from around the world, featuring this spot.)

Can you tell how cold and windy it was?

Which Shoes to Wear to The Burren

The winds were picking up and we were getting chilly, so we bustled back to the car, careful not to twist ankles on the knobby Burren “floor.” (Note: Wearing stiletto heels to the Burren would be the worst idea ever.) As we zipped down the rocky road, I felt the contented exhilaration of reuniting with an old friend. I’ll never look at that restaurant in Somerville the same way!

The Burren is quite unique, isn’t it?
