Gilroy is a city in Santa Clara County, California, United States. It is located south of the San Francisco Bay Area. In 2020, about 59,520 people lived there.
Gilroy started as a small village called San Ysidro in the early 1800s. This land was given to a rancher named Ygnacio Ortega in 1809. After he passed away, his daughter Clara and her husband, John Gilroy, took over most of the land. They began to develop the area.
In 1868, the town became official and was named after John Gilroy. He was a Scotsman who came to California in 1814. To own land in the Spanish Empire, he became a Mexican citizen, learned Spanish, and became Catholic. He then took the name Juan Bautista Gilroy.
Gilroy is famous for its garlic farms. It is even called the "Garlic Capital of the World"! The city is also known for its small, special wineries. These are mostly family-owned vineyards near the Santa Cruz Mountains.

Gilroy's Past: A Journey Through Time
Spanish Era: Early Explorers and Settlements
Spanish explorers first arrived in the Santa Clara Valley in 1776. This group was led by Juan Bautista de Anza. About 20 years later, Spanish missionaries built Mission San Juan Bautista in 1797. It was located near the Pajaro River.
In 1809, a large piece of land called Rancho San Ysidro was given to Ygnacio Ortega. It was about 13,066 acres (5,288 hectares). The village of San Ysidro grew near this rancho. It was at the foot of Pacheco Pass. This pass connected the El Camino Real (a main road) with the San Joaquin Valley. Back then, California mostly traded animal hides and fat. These were shipped to other parts of New Spain. Trading with foreigners was not allowed, but people still did it quietly to get fancy goods.
Mexican Era: John Gilroy's Story
During the War of 1812, a British ship called the Isaac Todd sailed to California. It stopped in Monterey, California in 1814. John Gilroy, a sailor from Scotland, was on this ship. He had changed his name from John Cameron to avoid being recognized. He either left the ship or was left behind because he was sick.
John Gilroy (1794–1869) became known as Juan Bautista Gilroy. For several years, he traveled between the missions, towns, and ranchos. He worked as a cooper, making barrels. He was one of the first two English-speakers in Alta California. He eventually settled at Rancho San Ysidro. He became Catholic and was the first English-speaking settler to become a Mexican citizen in Alta California.
In 1821, Mexico became independent from Spain. That same year, John Gilroy married Maria Clara, the daughter of his employer, Ygnacio Ortega. When Ygnacio died in 1833, his rancho was divided among his three children, including Maria Clara. In 1867, John Gilroy officially received the land under U.S. law.
The area now called "Old Gilroy" grew around Gilroy's rancho. After the Mexican–American War ended in 1848, Gilroy served as the mayor of the village. It was also a stop for stagecoaches in the late 1800s.
American Era: Growth and Garlic

After the U.S. took over California and gold was found in 1848, many people moved to the area. Mexican landowners often sold their land or lost it. The area around San Ysidro became known as Pleasant Valley. On March 12, 1870, the state officially made it the town of Gilroy. John Gilroy had passed away in 1869. By then, the town center had moved west of the old main road.
Raising cattle and cutting timber from the Santa Cruz Mountains were important jobs. But farming became the biggest source of money for the town. In the 1920s, Kiyoshi “Jimmy” Hirasaki started growing garlic for sale in Gilroy. He was known as the "Garlic King."
In 1979, the Gilroy Garlic Festival began. Farming is still important, but since the 1970s, Gilroy has also become a place where people live and commute to work in Silicon Valley.
There are many old buildings in Gilroy. The Christian Church at 160 Fifth Street was built in 1857. It is the oldest wooden church in Santa Clara County that is still used. George Eustice's house at 213 Fifth Street was built in 1869. He was a blacksmith and fought in the American Civil War. Samuel Moore, a long-time postmaster, built his home in the 1870s at 7151 Church Street.
Nearby, in the Diablo Range foothills, is the historic Gilroy Yamato Hot Springs. It was first developed in the 1870s but is now closed. In 1905, the Old City Hall was built downtown. It was added to the National Register of Historic Places in 1975.
Gilroy's Location and Weather

Gilroy covers about 16.2 square miles (42 square kilometers). Most of this is land.
Climate: Warm Summers and Mild Winters
Gilroy has a warm Mediterranean climate. This means it has hot, dry summers and mild, wet winters. The nearby Pacific Ocean helps keep temperatures from getting too extreme.

In summer, fog often rolls in from the ocean around 10 p.m. and clears by 10 a.m. the next morning. Gilroy can get hotter than areas to its north and west during summer afternoons. Winters have many sunny days with breaks between rainstorms. The area does not often have tornadoes, strong winds, or thunderstorms. The local plants are mostly chaparral and grasslands, with live oak trees in higher areas.
