Drive down State Route 63 in Warren County, past the sprawling industrial parks and the rising suburban rooftops, and you might miss it. Most people do. They're focused on getting to the Cincinnati Premium Outlets or heading into the historic heart of Lebanon for a slice of pie at the Golden Lamb. But tucked away, largely forgotten by the thousands of commuters who whiz by every day, sits the remains of Colony 7 Lebanon Ohio.
It’s an odd name, isn't it? It sounds like something out of a mid-century sci-fi novel or perhaps a communal living experiment that went south. In reality, it was a piece of the American Dream—albeit a very specific, Cold War-era version of it.
What Was Colony 7 Exactly?
To understand Colony 7, you have to look back at the 1960s and 70s. This wasn't just a random patch of dirt. It was originally developed as a private club and recreation destination. We're talking about a time when the "private club" model was the height of suburban luxury. It featured a massive swimming pool, tennis courts, and a clubhouse that served as a social hub for families in the Dayton and Cincinnati orbit.
But here is where things get weird.
While most people remember it as a defunct swim club, the site’s proximity to the former Glendower State Memorial and the general "hidden" nature of the property led to decades of local legends. Some people in Warren County will swear up and down that it had deeper ties to the military or government projects, likely because of its era and the somewhat secretive "members only" vibe it maintained for years.
The truth is a bit more grounded but no less interesting. Colony 7 was a victim of the changing American lifestyle. As public parks got better and backyard pools became affordable for the middle class, the "private colony" model started to suffocate.
The Decay of an Ohio Landmark
If you try to visit today, don't expect a welcome mat. Most of the original structures associated with the Colony 7 Lebanon Ohio site have either been reclaimed by the thick Ohio brush or leveled for safety.
I remember talking to a local photographer who managed to get onto the perimeter a few years back. They described a scene that was pure "Life After People." The concrete basin of the pool was cracked, with saplings growing through the deep end. The locker rooms were shells.
It's spooky.
Honestly, the site serves as a physical reminder of how quickly "the next big thing" in real estate becomes a liability. By the late 80s and early 90s, the property had transitioned from a bustling social center to a headache for local zoning officials. It sat in a sort of legal and developmental limbo for a long time.

Why People Keep Bringing It Up
The fascination persists because of the "closed gate" mystery.
Humans hate a secret. When you put a fence around 40 acres and call it "Colony 7," people are going to speculate. Over the years, I've heard everything from "it was a fallout shelter for local elites" to "it’s haunted by a disgruntled former lifeguard."
None of that is true, of course.
The real story is about land use. The area around Lebanon has exploded in value. What was once "the middle of nowhere" is now prime real estate. Developers have looked at the Colony 7 land for years, eyeing it for everything from high-end housing to commercial warehouses. Yet, every time a plan comes up, the ghost of the old colony seems to stall it out.
The Cold War Context
You can't talk about Colony 7 Lebanon Ohio without mentioning the Nike Missile sites that dotted this region. While Colony 7 itself wasn't a missile silo, the feeling of that era is baked into the dirt there.
Southwestern Ohio was a massive target during the Cold War. Between Wright-Patterson Air Force Base and the various atomic energy plants (like Mound in Miamisburg), the whole region was on edge. Places like Colony 7 provided a literal and figurative escape. It was a gated community before gated communities were a standard suburban trope.
It offered a sense of security.
If you lived in Lebanon or Mason in 1972, being a member at Colony 7 meant you had "arrived." You had a place where your kids could run wild in a controlled environment while you sipped a drink by the pool. It was the peak of the Eisenhower-era dream deferred into the 70s.
Navigating the Legal and Physical Ruins
Today, the site is private property. Do not go trespassing there. Seriously.

Local law enforcement in Lebanon and the Warren County Sheriff’s Office are well aware that "urban explorers" love to poke around old ruins. They aren't amused by it. Most of what made the site "Colony 7" is gone anyway, replaced by the mundane reality of overgrown fields and maybe a few rusted pipes sticking out of the ground.
The real "Colony 7" exists in the memories of the Baby Boomers who grew up there.
- They remember the smell of chlorine and snack bar hot dogs.
- They remember the sound of the screen door slamming at the clubhouse.
- They remember the heat of the Ohio summer on the asphalt parking lot.
The Development Struggle
Why hasn't it been turned into a Target or a subdivision yet?
Infrastructure is usually the culprit. Bringing modern sewage, water, and high-speed internet to a site that has been stagnant for decades is expensive. Lebanon has strict building codes. The city is proud of its history—from the Shakers to the golden age of the railroad—and they don't just greenlight every project that comes across the desk.
There's also the issue of environmental remediation. Old pools and clubhouses often come with "gifts" like asbestos or old lead piping. For a developer, the cost of cleaning up the Colony 7 Lebanon Ohio footprint often outweighs the immediate profit of building ten new homes.
What Most People Get Wrong
The biggest misconception is that Colony 7 was a "failed" venture from the start.
It wasn't. It was actually quite successful for a long time. It only "failed" because the world around it changed. We stopped wanting to belong to "colonies" and started wanting to stay in our own air-conditioned living rooms.
Also, it wasn't a cult. I've seen that pop up on Reddit threads more than once. Just because a place has "Colony" in the name and a fence around it doesn't mean people were chanting in the woods. It was just a fancy name for a country club that didn't have a golf course.
How to Find Trace Evidence
If you're a history nerd, you can still find the "ghost" of the site through public records and old maps.

- Check the Warren County Auditor’s site. You can trace the deed transfers back decades.
- Look at aerial photography from the 1970s (available through some University of Cincinnati archives). You can see the original layout of the pool and the tennis courts.
- Visit the Warren County Historical Society in downtown Lebanon. They have files on local businesses and social clubs that often include brochures or newsletters from the Colony 7 era.
Seeing the grainy, black-and-white photos of families smiling by the pool really puts it into perspective. It wasn't a mystery then. It was just home.
Final Practical Steps for History Buffs
If you want to experience the history of Lebanon without getting a trespassing ticket, there are better ways to spend your afternoon.
First, go to the Warren County Historical Society. It’s one of the best local museums in the state. They can give you the actual context of the 1960s development boom in the area.
Second, drive the perimeter of the area near SR 63 and Gateway Blvd. You can see how the industrial world is slowly encroaching on the old green spaces. It gives you a sense of the scale.
Third, talk to the locals at the Village Ice Cream Parlor. There’s almost always someone at the counter who grew up in the area and remembers when Colony 7 was the place to be. Their stories are better than any "paranormal" YouTube video you'll find.
The story of Colony 7 Lebanon Ohio isn't about ghosts or government secrets. It's a story about how we used to live, how we used to play, and what we leave behind when we move on to the next suburb. It’s a quiet piece of Ohio history that’s slowly being paved over, one square foot at a time.
If you're interested in exploring more local history, your next step should be researching the Nike Missile Site CD-46 which was located nearby. It provides the perfect military-industrial counterbalance to the private-club lifestyle of Colony 7, giving you a complete picture of what life was like in Warren County during the height of the Cold War. You can find maps and veteran accounts online that detail exactly how these sites protected the Cincinnati-Dayton corridor.
