If you’ve spent any real time walking the sand along the Ocean Boulevard stretch in Long Beach, California, you’ve probably stopped dead in your tracks. There, nestled among the contemporary beachfront builds and the swaying palms, sits a structure that looks like it was ripped straight out of a Grimm’s fairy tale. It's the fantasy castle Long Beach residents have whispered about for decades. Some call it the "Treasure Island" house. Others just call it "that weird castle on the beach."
It isn't a theme park. It isn't a movie set left over from the 1920s. It’s a private residence with a history that is honestly weirder than the architecture itself.
Most people think it’s just a eccentric millionaire’s whim. They’re halfway right. But the "Fantasy Castle," officially known as the Dona Sol, represents a specific era of Long Beach history where the city was trying to find its identity between being a Navy town and a glamorous resort destination. Located at 2515 East Ocean Boulevard, it stands as a defiant middle finger to the boring, beige stucco boxes that dominate so much of the Southern California coast.
The Weird History of the Fantasy Castle Long Beach Loves to Gossip About
You can't talk about this place without talking about the 1920s. This was the "Golden Age" for Long Beach. Back then, the city was the "Waikiki of the West." The castle was built around 1924, a period when "Period Revival" architecture was all the rage. People weren't just building houses; they were building fantasies.
The original owner, a man named C.T. McGrew, was a prominent builder in the area. He didn't just want a home; he wanted a statement. He used stone and masonry to create those iconic turrets and the rugged, uneven facade that makes it look like it’s been weathering North Sea storms for five hundred years rather than sitting in the sunny 562.
But here is the thing: it almost didn't survive.
In 1933, a massive earthquake leveled much of Long Beach. It was a disaster that redefined California building codes forever. While brick buildings all around the downtown area were crumbling into piles of dust, the Fantasy Castle stood its ground. Its heavy masonry, which looks purely decorative, was actually remarkably sturdy. This survival added to the local mythos. People started believing the house was "protected" or somehow fundamentally different from the rest of the neighborhood.
Architecture That Defies Logic
Let’s get into the weeds of why this place looks the way it does. It’s technically a French Normandy style house, but that’s a bit of a polite understatement. It’s got "clinker" bricks—those are the burnt, misshapen bricks that most builders used to throw away until architects realized they looked cool and "antique."
The roof is a steep, conical nightmare for any modern roofer. The windows are small and leaded. It has that specific kind of "storybook" charm that influenced the early look of Disneyland. Honestly, if you told me Walt Disney took a stroll past this house before designing Fantasyland, I’d believe you, though there's no official record of that specific inspiration.
The interior is just as wild. We're talking about heavy timber beams, massive stone fireplaces, and rooms that feel more like a dungeon (in a cozy way) than a living room. It’s a far cry from the "open concept" floor plans everyone is obsessed with today. It’s dark. It’s moody. It’s cramped in some spots and soaring in others.
One of the most striking features is the observation deck. Back in the day, you could see the entire coastline from there. Today, the view is a bit more obstructed by neighboring mansions, but the vibe remains. It’s the kind of place where you expect to see someone looking out for pirate ships, even if they're actually just looking for a parking spot on Ocean Blvd.
Why People Keep Confusing It With Other "Castles"
There’s a lot of misinformation out there. I've seen TikToks claiming this was built by a silent film star for his mistress. I've seen Reddit threads insisting it’s haunted by a sea captain.

Kinda. But mostly no.
Long Beach has a few "castle-like" structures. You have the Villa Riviera, that massive green-roofed Gothic building further down the coast. People often conflate the two in local lore. The Villa Riviera is an apartment building (and a giant one at that), while the Fantasy Castle is a single-family home.
Then there's the confusion with the "Spadena House" (The Witch’s House) in Beverly Hills. They share a similar Storybook style, leading many tourists to think they were designed by the same person. They weren't. The Fantasy Castle is a uniquely Long Beach product of the McGrew family’s ambition.
Life Inside a Local Legend
What’s it actually like to live there? Well, it isn't easy.
Living in a landmark means dealing with the "Looky-loos." If you live in the Fantasy Castle, you are essentially a public exhibit. People park their bikes in front of your gate. They take engagement photos on your sidewalk. They try to peek through the leaded glass.
Maintenance is also a total bear. You can’t just go to Home Depot and buy a replacement window for a 1920s French Normandy turret. Everything is custom. Everything is expensive. The salt air from the Pacific Ocean is constantly trying to eat the stone and the mortar. It requires a homeowner who isn't just rich, but who is a genuine steward of history.
Over the years, the home has changed hands. Each owner has added their own flair, but the core structure remains remarkably untouched. It’s one of the few places in Long Beach that hasn't been "modernized" into a sterile white box. Thank god for that.
The Cultural Impact on the Bluff
The Fantasy Castle sits on the Bluff Park neighborhood, which is arguably the most prestigious stretch of real estate in the city. This area is a protected historic district. Because of the castle’s presence, the neighborhood feels anchored in a different time.
It serves as a landmark for runners on the beach path. "I’ll meet you at the castle" is a common phrase for local marathon trainers. It’s a waypoint. It’s a piece of the city’s soul that reminds us that architecture doesn't always have to be practical or "efficient." Sometimes, it can just be fun.

Actionable Tips for Visiting (Respectfully)
If you’re planning to head down to see the fantasy castle Long Beach is so proud of, don't just wing it.
- Parking is a nightmare. Don't even try to park on Ocean Blvd on a weekend. Use the public lot at the foot of Junipero Ave and walk up the stairs. It’s a better view anyway.
- Golden Hour is the play. The way the setting sun hits the textured stone of the turrets makes for the best photos.
- Respect the privacy. It’s a home. People live there. Don't lean on the fence, and definitely don't try to go inside. The best view is from across the street on the bluff path.
- Check out the neighbors. While the castle is the star, the surrounding homes in Bluff Park are incredible examples of Craftsman, Spanish Colonial, and Mid-Century Modern architecture.
How to Dig Deeper into Long Beach History
If this house sparked an interest in you, the next step isn't just staring at the gate.
Check out the Long Beach Historical Society. They have archives that include original building permits and photos of the Ocean Boulevard coastline before it was built up. It’s wild to see the "Fantasy Castle" sitting almost alone on a ridge of sand dunes.
You should also look into the Long Beach Architecture Week (usually held in the spring). They often feature walking tours of Bluff Park. While they don't always get you inside the castle, the guides are usually local historians who know every dirty little secret about the families who built these mansions.
Understanding the Fantasy Castle is about understanding that Long Beach has always been a little bit "extra." It’s a city that built a giant ocean liner (the Queen Mary) and decided to keep it forever. It’s a city that built a house that looks like a castle just because it could.
Stop looking at the boring new condos. Walk down to 2515 East Ocean. Look at the turrets. Imagine the 1920s parties. That’s the real Long Beach.
To get the most out of your visit, pair a walk past the castle with a trip to the Long Beach Museum of Art, which is just a few blocks away. It’s housed in another historic mansion (the Elizabeth Milbank Anderson house) and offers a similar glimpse into the "Grand Old Days" of the shoreline. This gives you a complete perspective on the architectural evolution of the bluff, moving from private fantasy to public cultural space.
