Underground Development

There Was More Underground than Above Ground

During the California heat wave of 1906, Baldassare Forestiere dug a home underground with just a pickax and shovel. He spent 40 years excavating 10 acres of rooms, tunnels, a chapel, an underground aquarium, and courtyards to experiment with underground farming. With no budget, he mixed mortar from the dirt he dug out, creating his own concrete and bricks. Despite continuing to work as a day laborer during the day (mostly digging irrigation ditches), by the 1920s, he had completed about 50 subterranean rooms.
