A marvel of both human determination and architectural brilliance, this subterranean sanctuary offers a fascinating escape from the ordinary.

1. A Century-Old Masterpiece Built by One Man’s Hands

One of the most remarkable aspects of the Forestiere Underground Gardens is its origin story. It all began in the early 1900s when Baldasare Forestiere, a Sicilian immigrant, arrived in California with a dream. Initially intending to grow citrus trees, Forestiere quickly realized the Fresno soil and the region’s intense summer heat posed significant challenges.

Rather than give up, Forestiere adapted—by digging. What began as a simple attempt to escape the sweltering heat eventually evolved into a massive subterranean network of courtyards, passageways, and rooms—all excavated by hand using only shovels, picks, and wheelbarrows. Over the course of 40 years, Forestiere chiseled out more than 10 acres of underground space, including living quarters, gardens, and even a fish pond.

The underground structure is not just functional—it’s poetic. It reflects the Old World architecture of Roman catacombs, harmoniously blending form and function. From arched passageways to open-air skylights, the space was designed to maximize comfort, light, and ventilation—long before the invention of air conditioning.

What’s even more astonishing? Forestiere had no formal training in engineering or architecture. Yet his creation has stood the test of time and remains a tribute to human innovation, endurance, and passion.

2. Architecture That Responds to the Earth

What sets Forestiere Underground Gardens apart isn’t just that it’s underground—it’s how seamlessly the architecture interacts with the environment. The structure is a masterclass in sustainable and passive design. The subterranean depth keeps the interior remarkably cooler than the scorching Fresno summer above—sometimes as much as 30 degrees cooler.

The rooms were carved out at different depths to regulate temperature and airflow naturally. Skylights and strategically placed windows draw in sunlight while facilitating cross-ventilation. Rainwater harvesting systems and built-in irrigation channels show just how forward-thinking Forestiere was, well ahead of the green-building movements of the modern age.

Each room serves a specific purpose—some were bedrooms, others dining spaces, and some were greenhouses. Many of the rooms are adorned with rustic stonework, arches, and grapevine trellises. Some rooms even feature furniture carved directly into the stone walls, showcasing Forestiere’s resourcefulness.

Whether you’re an aspiring architect, designer, or someone who enjoys clever spatial planning, the Forestiere Gardens reveal something new around every bend. Every twist of the hallway holds a surprise, be it a flowering vine, a centuries-old citrus tree, or a peaceful courtyard brimming with life and natural light.

3. Hidden Passages, Secret Rooms, and Living History

The deeper you explore, the more you realize: this isn’t just a series of tunnels—it’s an entire lifestyle carved into the Earth. Forestiere didn’t just build a shelter; he built a home, complete with bedrooms, kitchens, parlors, and even a chapel.

As you walk through the passageways, you’ll discover areas of the underground gardens that few expect to find—like a summer bedroom and a winter bedroom, each positioned for seasonal comfort. Or a fish pond dug deep into the floor, once stocked with tilapia and surrounded by citrus trees.

There’s even a “man cave” of sorts—a cozy den where Forestiere spent evenings reading by lamplight. These features offer a more intimate look into the man behind the marvel, painting a picture of someone deeply connected to both nature and solitude.

But there are also plenty of hidden gems that even repeat visitors may miss. For example, one passageway leads to a tiny wine cellar tucked behind a stone arch. Another opens into a sunken garden, a quiet escape surrounded by flowering plants and buzzing bees.

And because the site remains largely unchanged from the time Forestiere last worked on it in the 1940s, it serves as a time capsule of early 20th-century immigrant life in California. The tools Forestiere used are still on display, and many of his original design choices are lovingly preserved.

Insider Tip:
Ask a guide about the “Secret Library Nook”—a favorite hideaway where Forestiere used to read during the cooler months. It’s not part of every tour, so you may need to request it!
