The Ohio State Stone Laboratory – Science, History, and Discovery on Gibraltar Island

A Hidden Gem in Lake Erie’s Waters, Just Off the Shores of Put-in-Bay

Tucked away just north of downtown Put-in-Bay lies Gibraltar Island, a tiny but historically rich and scientifically vital piece of land. Home to The Ohio State University’s Stone Laboratory, this island has played a pivotal role in protecting the health of Lake Erie and educating generations of freshwater researchers, students, and nature lovers.

For over a century, this special place has been where science meets the shoreline—where problems like harmful algae blooms and invasive species are not only studied but actively solved. Thanks to the tireless work of scientists, faculty, and students, Lake Erie is healthier today than it’s been in decades.

 

Visiting the Stone Lab on Gibraltar Island

If you’re looking to explore something truly unique during your visit to Put-in-Bay, a tour of Gibraltar Island and Stone Lab is a must.

🛥️ Getting There

Gibraltar Island sits in the Put-in-Bay harbor, easily visible from downtown. Access is simple thanks to:

A Storied Past: The History of Gibraltar Island and Stone Lab

Long before it became a hub for freshwater research, Gibraltar Island was the summer retreat of Jay Cooke, a wealthy financier who helped fund the Union during the Civil War. In 1864, Cooke began developing the island, starting with the building now known as Stone Lab.

The centerpiece of the island, Cooke Castle, came shortly after. Constructed from local limestone, this Gothic-style home is now a historical landmark. Though tours only explore the exterior currently, efforts are underway to renovate Cooke Castle into a special event venue. The Ohio Sea Grant, in partnership with Friends of Stone Lab and Ohio State, are actively fundraising to restore this gem.

 

Stone Lab’s Vital Research and Student Programs

Stone Laboratory isn’t just a pretty place—it’s one of the foremost freshwater field research stations in the country.

Each summer, students from across Ohio and beyond receive scholarships to study here. They attend specialized courses and gain hands-on experience working directly with professional researchers.

Together, they tackle some of the biggest challenges facing Lake Erie, including:

– Harmful algal blooms

– Invasive species

– Water quality and conservation efforts

The Stone Lab community has made incredible strides in improving the health of the lake, and their work ensures that future generations can continue to enjoy its natural beauty.
