Top 5 Things You May Not Know About Allison Island

Racetrack Roots, Waterfront Perks

Did you know that before Allison Island became a luxury address, it was a personal tribute to the founder of the Indianapolis Motor Speedway and a key figure in early automotive innovation?

Created by Carl Fisher in 1912, the island, contrary to popular belief, wasn't another dredged-up land grab — Fisher named it after his close friend and fellow speed enthusiast, James "Jim" Allison, a famous personality who co-founded the Indianapolis Motor Speedway and made his fortune in the automotive and precision manufacturing industries.

So yes, a guy who loved fast cars ended up leaving his mark on a laid-back island paradise. 

If you think about it, Allison Island is probably the only Miami Beach neighborhood with a pit stop in racing history.

Hospital with a Side of Caviar     

Believe it or not, Allison Island's first claim to fame wasn't its estates but its five-star hospital. 

In the 1920s, Jim Allison dreamed of building a luxury sanatorium where wealthy snowbirds could recover from ailments in style. 

We're talking Spanish-style architecture, ocean-view terraces, and gourmet meals on fine china with sterling silver flatware. 

The hospital even hired a chef from New York's Waldorf-Astoria to cook for the patients — apparently, nothing speeds up recovery like lobster bisque and panoramic views. 

It's safe to say that the hospital food on Allison Island peaked early and has never been the same since then.

Swapping Nuns for Nautical Mansions

Looking for drama? We'll give you drama — but not the kind you see on midday television!

After Jim Allison's death (following a chaotic marriage-honeymoon combo), his lavish hospital passed into the hands of the Sisters of St. Francis. 

For decades, Allison Island was more about quiet prayers than wild parties. 

But by the 1990s, developers had other plans that led to the hospital being torn down and Allison Island being reborn as a luxury residential enclave. 

In other words, the island went from rosaries to real estate, and now, the only thing being worshipped is the view.

Architecture With a Personality Crisis (In a Good Way)

Most gated islands pick a lane — Mediterranean mansions, modern glass palaces, or tropical villas. 

Not Allison Island.

Thanks to the Aqua development, the island's southern half became a design playground for famous architects. 

Here, each of the three mid-rise condo towers has a different look, from a floating glass base to a compass-inspired layout. 

Throw in 46 custom-designed townhomes, each with its own quirky twist, and you get a neighborhood that doubles as an architectural scavenger hunt. 

Who knew luxury could have so much personality?
