The Forestiere Underground Gardens are a network of underground rooms, gardens, and grottoes. Institutions of higher education include Fresno City College and California State University, Fresno. The largest of Fresno's city parks is Roeding . In the park are athletic fields and a zoo. In the irrigated fields surrounding Fresno, grapes, cotton, and figs are grown.
Food processing is the area's major industry.
Grapes are crushed to make wine and are dried to make raisins in one of the world's largest dried-fruit processing plants. The manufacture of farm machinery, transportation equipment, and vending machines is also important. Because the Fresno area was hot and dry, both Spanish and Mexican settlers avoided it. In the 1860s a Dutchman named A. J. Manssen settled there and dug a well. He was joined by a few other settlers.
