Walk into Touro Park in the middle of Newport, and you'll see it. It’s a stone cylinder, perched on eight rounded arches, looking like it belongs in a medieval European village rather than a seaside town in New England. This is the Newport Tower Rhode Island locals and tourists have been scratching their heads over for centuries. Some call it the Old Stone Mill. Others think it’s a remnant of a Viking settlement or a secret temple built by the Knights Templar.
Honestly, the "mystery" is the only thing everyone agrees on.
If you ask the average passerby, they’ll probably tell you a version of the story they heard from a tour guide or a YouTube rabbit hole. But the actual history is a messy mix of carbon dating, colonial records, and wild archaeological theories that refuse to die. It's a weird piece of architecture. There’s no getting around that. Why build a windmill on arches? Why are the windows aligned with the stars? It feels intentional. It feels old. But "how old" is the question that has turned mild-mannered historians into bitter rivals.
The Colonial Reality vs. The Viking Fantasy
The most widely accepted explanation is pretty straightforward, even if it’s a bit of a letdown for the treasure-hunter types. Most mainstream historians argue the Newport Tower Rhode Island was just a windmill built by Benedict Arnold. No, not that Benedict Arnold—this was the great-grandfather of the infamous Revolutionary War traitor. He was the first governor of the Rhode Island colony and owned the land where the tower stands.
In his will, written in 1677, Arnold specifically mentions "my stone built wind-milln."
That seems like a smoking gun, right? Case closed. But the fringe theorists haven't budged. They point out that the masonry doesn't look like other 17th-century colonial structures. They argue that Arnold might have just been repurposing a building that was already there. You’ve probably seen the "Viking" theory mentioned in travel brochures. In the 1830s, Danish archaeologist Carl Christian Rafn suggested the tower was part of a Norse settlement from the 12th century. It’s a cool idea. It sells t-shirts. But there hasn't been a single Norse artifact—not a coin, not a tool, not a scrap of iron—found anywhere near the site.
What the Carbon Dating Actually Told Us
In 1993, a team of Danish researchers (ironically, the same nationality as the guy who started the Viking rumor) performed radiocarbon dating on the mortar used in the tower. This was supposed to be the definitive "gotcha" moment.
The results were interesting.

The analysis placed the construction of the tower somewhere between 1635 and 1698. This fits perfectly with the timeline of Benedict Arnold and the early Rhode Island settlers. The lime used in the mortar came from local shells, and the carbon-14 levels pointed directly to the 17th century.
So, that’s it? Not quite.
The "Newport Tower Rhode Island" loyalists, specifically those who believe in pre-Columbian contact, argue that the carbon dating only proves when the tower was repaired or mortared, not when the stones were first stacked. They suggest the core structure could be hundreds of years older. It's the kind of argument that keeps historians awake at night. Basically, if you want to believe it’s a Templar church, carbon dating isn't going to stop you.
The Weird Geometry of the Tower
One of the reasons the Newport Tower Rhode Island persists as a mystery is the "archaeoastronomy" involved. William Penhallow, a professor of physics at the University of Rhode Island, spent years studying how light hits the tower.
He found something genuinely spooky.
During the winter solstice, the sun shines through a specific window and hits a stone on the opposite side of the tower. There are also alignments for the lunar "minor standstill" and other celestial events. Why would a 17th-century farmer care about lunar cycles enough to bake them into the architecture of a windmill?
Maybe he wouldn't. Or maybe, as some suggest, Benedict Arnold was a member of a learned society and just thought it would be cool. Or maybe it's all a coincidence. Humans are great at finding patterns in random piles of rocks. You see a window; a physicist sees a solar observatory. Both could be right. Or both could be wrong.

The tower's design—eight pillars forming a rotunda—is also remarkably similar to "round churches" found in Europe, like the Church of the Holy Sepulchre in Jerusalem or various Templar chapels. This is the fuel for the Knights Templar theory. Supporters like Scott Wolter, host of America Unearthed, argue the tower was part of a 14th-century mission to the New World.
The Physical Evidence (Or Lack Thereof)
If you walk around the base of the tower today, you’ll see it’s fenced off. You can’t go inside. This is to protect the structure, which has taken a beating from the New England weather over the last 350+ years.
Several excavations have happened in Touro Park:
- 1948-49: The first major dig. They found 17th-century colonial pottery and pipes but nothing older.
- 2006: A team used ground-penetrating radar. They found some anomalies under the soil, but nothing that screamed "Viking hoard."
- Recent Observations: Researchers have noted that the tower sits on a foundation of "floating" stones rather than a deep trench, which was a common technique for colonial structures in the area.
It's kind of frustrating. Every time someone tries to prove the tower is ancient, they find more evidence that it’s just really old. There is a big difference between "1300s" and "1600s," even if both feel like ancient history to us.
Why We Can't Let the Mystery Go
The Newport Tower Rhode Island is a mirror. People see what they want to see in it.
If you’re a romantic, you see a remnant of a lost civilization or a secret voyage across the Atlantic. If you’re a skeptic, you see a poorly designed windmill that didn't even work very well (some records suggest it was abandoned because the wind didn't catch the sails right due to the nearby trees).
There's something uniquely American about this. We’re a relatively young country, and we’re desperate for deep roots. We want our history to be longer and more mysterious than it actually is. The idea that a group of medieval knights or Norse explorers stood on a hill in Rhode Island long before Columbus is addictive. It changes the narrative of who "found" this place.

But even if it's just a windmill, it’s a magnificent one. Think about the labor required to haul those stones and set those arches without modern machinery. Even as a 17th-century relic, it’s one of the most unique buildings in North America.
How to See the Tower for Yourself
If you're heading to Newport, don't just look at the mansions on Bellevue Avenue. The tower is just a short walk away.
Location: It’s in Touro Park, right at the intersection of Bellevue Avenue and Pelham Street.
Cost: It’s free. It’s a public park.
Best Time to Visit: Go during the late afternoon. The way the shadows fall through the arches is when you really start to understand why people think it’s a mystical site.
When you get there, look at the "keystones" in the arches. Look at the irregular placement of the windows. Try to imagine a giant wooden cap and sails on top of it. Does it look like a mill? Or does it look like something else?
Actionable Steps for Your Visit
- Check the Alignments: If you happen to be in Newport during a solstice or equinox, bring a compass. It’s fascinating to see how the light interacts with the inner walls.
- Visit the Newport Historical Society: They have actual artifacts from the excavations. Don't just take a blogger's word for it—see the colonial pipes and pottery for yourself.
- Compare it to the Chesterton Windmill: Google the "Chesterton Windmill" in Warwickshire, England. It was built in 1632 and sits on similar stone pillars. It looks remarkably like the Newport Tower. This is often cited as the inspiration for Benedict Arnold’s design.
- Walk the Neighborhood: Newport is one of the best-preserved colonial towns in the country. Seeing the tower in the context of the nearby 17th-century houses helps ground the mystery in reality.
The Newport Tower Rhode Island doesn't need to be a Viking temple to be incredible. It’s a survivor. It’s weathered hurricanes, wars, and the urban development of a busy city. Whether it was built by a governor with a flair for the dramatic or a sailor from a distant land, it remains the strangest pile of rocks in New England.
Next Steps for History Buffs:
Check the local library records for the 1948 excavation report by Godfrey. It’s dry, but it’s the most honest look at what lies beneath the dirt. Also, keep an eye on the New England Antiquities Research Association (NEARA) for any upcoming lectures; they’re usually the ones spearheading new (and often controversial) research into the tower's origins.
