Details
Located in the heart of Fresno, California, Forestiere Underground Gardens offers a distinct escape beneath the Central Valley’s sunbaked surface. This intricate network of hand-dug subterranean rooms, passageways, and groves was carved out by Baldassare Forestiere over three decades starting in the early 1900s. The gardens prove a remarkable feat of sustainable ingenuity, designed to provide cool refuge, vibrant citrus groves, and natural ventilation amid the region’s intense summer heat.
Visitors begin their journey with a guided tour that reveals the astonishing architectural creativity and agricultural knowledge embedded in every tunnel and chamber. The gardens combine elements of naíve art, functional design, and California’s agricultural roots, with grape vines, fig trees, and oranges growing in sunken courtyards below ground. The earth itself forms sculpted arches and skylights that funnel filtered light into this hidden world. Tour guides like Kai or Lashika bring the story to life through engaging narratives, highlighting Forestiere’s immigrant heritage, the manual labor involved, and the garden’s ongoing preservation.
Beyond the historical and horticultural appeal, events such as Underground Overture — an immersive sound experience — add a contemporary edge, turning these ancient earthen chambers into a natural amphitheater. The gift shop onsite offers memorabilia, while the gardens’ cool microclimate makes it a comfortable stop even on warm Fresno days.
Forestiere Underground Gardens stands out as a unique blend of art, history, and nature that embodies the inventive spirit of Central California. For travelers and locals alike, it offers a rare peek into an subterranean sanctuary that feels both otherworldly and deeply rooted in its environment.
