Forestiere Underground Gardens 


The Forestiere Underground Gardens, located at 5021 West Shaw Avenue in Fresno, California, are a series of subterranean structures built by Baldassare Forestiere , an immigrant from Sicily, over a period of 40 years from 1906 to his death in 1946. The gardens are currently operated by members of the Forestiere family through the Forestiere Historical Center, and can be considered a spectacular and unconventional example of vernacular (ie; without professional guidance) architecture.

Yosemite National Park to Bear Valley   Map

After doing some map research, we had decided to take a somewhat different route to Santa Barbara, where we drove west on route 120 to Groveland and then turned south on route 49 through Mariposa. On the way to Mariposa, we passed through an area known as "Bear Valley" where the famous John C. Fremont used to own several gold mines.

As you can see in these images, this part of California is desolate and the marker for the Fremont Fort marks the location where John C. Fremont built a fort to protect his gold mines. This part of California history is fascinating, click here to read the full story on Wikipedia.

Breakfast in Mariposa   Map

Our original idea for breakfast was to have stopped in Groveland on route 120 before we turned south on route 49. However, we discovered that either we were there way too early, or COVID had closed everything up - so we kept driving until we got to Mariposa.

As can be seen in these images, Mariposa is not a large town (population 1,186) but they have one of the best donut shops we've been to in a while! Donuts A-Go-Go has excellent coffee and a nice range of donuts and other pastries. The staff we interacted with were very nice and fun to talk to !

Quick History: When California was formed in 1850, Mariposa County was one of the original 27 counties and covered one-fifth of the entire state. The County was reapportioned to create all of parts of 11 other counties giving rise to the nickname the "Mother of Counties."

Once we had our donuts & coffee and checked the rental car over, we pushed on towards Fresno on route 99 with the goal of reaching Santa Monica by late afternoon.

Exploring the Forestiere Underground Gardens   Map

There are so many amazing facts about Baldassare Forestiere and how he created this underground garden, but you have to first remember that this entire excavation was created while he wasn't at his day job. Fresno's day time temperatures are generally high, and even though his excavations took place at night, remember that he was working in the evening, tired and by himself.

The underground gardens feature nearly one hundred chambers, passageways, courts and patios. Fruit-bearing trees planted below the ground protrude through openings at ground level. Forestiere resided here, benefiting from cooler temperatures during the high heat of the California Central Valley in summer as well as warmer conditions within the ground during winter.

The dirt that Forestiere excavated was moved to create the large structure was utilized elsewhere to fill planters, create stones placed within the catacombs, and to level out other parts of the land. The pathways and rooms were constructed with various widths to help direct airflow by creating pressure as it moves through narrower portions and maintain movement as it bounces off the slants and curves of the cavernous walls. The conical skylights allow for the hot air to be pushed out more quickly and the cool air to remain below.

One interesting note to remember - Forestiere had no formal training with plants, or citrus farming or tunneling!

Forestiere Underground Gardens Citrus/Fruit Plants

The garden's plants and trees, some of which are over 100 years old, are protected, by virtue of construction, from the frost in the winter months. Each level was planted at different times, so they bloom in succession, in order to lengthen the growing season. The garden houses a variety of fruit ranging from citrus and berries to exotic fruits like the kumquat, loquat, and jujube. The trees have been grafted to bear more than one kind of fruit, allowing for a larger variety to be grown throughout the space. Trees and vines were also planted above the dwelling, acting as insulation and forming canopies that provide protection from the elements.

Forestiere Underground Garden Tour

The Garden Tour requires reservations, and once your group is taken inside to the shop, you will then be taken to the main ballroom where the tour guide will give you the history of Baldasare Forestiere and his amazing underground garden. The tunnel goes through his living areas and many of the plants growing areas as well. The tour & guide was very informative and you will be glad you came there.

The Forestiere Underground Garden is listed on the National Register of Historic Places, and is also registered as No. 916 on the list of California Historical Landmarks.
