San Luis Obispo (Spanish for 'St. Louis the Bishop'; /sæn ˌluːɪs əˈbɪspoʊ/ san-_-loo-ISS-_-Ə-biss; Spanish: [san ˈlwis oˈβispo]; Chumash: tiłhini) is a city in California, USA. It is the main city of San Luis Obispo County. The city is located on the Central Coast of California. It is about halfway between the San Francisco Bay Area and Greater Los Angeles. In 2020, about 47,063 people lived there.
San Luis Obispo was started by the Spanish in 1772. This was when Saint Junípero Serra built Mission San Luis Obispo de Tolosa. The town grew during the time Mexico controlled the area. It expanded quickly after California became part of the United States. San Luis Obispo is a popular place for tourists. People visit for its old buildings, vineyards, and friendly atmosphere. It is also home to California Polytechnic State University, San Luis Obispo.

History of San Luis Obispo
Early Native American Life
The first people to live in this area were the Chumash people. They lived in villages and used resources from the ocean. Some of their early villages were near today's Los Osos and Morro Creek.
The Mission Period
In 1769, Spain wanted to spread the Catholic faith in Alta California. Junípero Serra, a Franciscan priest, was sent to do this. He founded the first Spanish mission in California, Mission San Diego, that same year.
In 1769, an expedition led by Gaspar de Portolá explored the San Luis Obispo area. One of the explorers, Padre Juan Crespí, named the area Cañada de Los Osos, which means "Valley of the Bears."
In 1772, people at the Presidio of Monterey were running out of food. Pedro Fages, a commander, led a hunting trip to the Valley of the Bears. They brought back a lot of bear meat and seeds. The local people were amazed at how easily the Spanish hunted the large grizzly bears.
After this, Junípero Serra decided the Valley of the Bears was a great place for a new mission. It had plenty of food, water, and a mild climate. The local Chumash were also very welcoming.
On September 1, 1772, Junípero Serra held the first Mass near San Luis Creek. The next day, he left Father José Cavaller to build the mission. Father Cavaller, five soldiers, and two native helpers started building Mission San Luis Obispo de Tolosa. This mission later became the city of San Luis Obispo.
The first mission buildings were made from local materials. Later, stronger buildings were built with adobe walls and tile roofs. The mission included a church, homes for priests, storage rooms, and barracks for soldiers. It also had a mill, a tannery, and land for farming and animals. The community worked together to produce everything they needed.
When Mexico fought for independence from Spain in 1810, the California missions had to support themselves. After Mexico won independence in 1821, there were calls to remove the Spanish priests and take over the missions. This process, called secularization, happened in the mid-1830s.
Ranchos and Town Growth
After 1834, the mission became a regular church. Most of its large land holdings were divided into ranchos, which were land grants. The main community stayed in the same spot and became the center of San Luis Obispo.
After the Mexican–American War, California joined the United States. San Luis Obispo was the first town to become a city in the new San Luis Obispo County. It has remained the county's center ever since.
In the early American period, the area was known for cattle ranching. The discovery of gold in California made beef prices go up, which helped the county's economy. But a drought in 1863 ruined most ranchos. People then started focusing on dairies, farming, and mining instead of just cattle.
San Luis Obispo also had a Chinatown near Palm and Chorro Streets. Chinese workers were brought here by Ah Louis to build the Pacific Coast Railway and other roads. They also dug tunnels through Cuesta Ridge for the Southern Pacific Railroad. Chinatown was a lively area with Chinese-owned businesses. Today, only the Mee Heng Low chop suey shop remains. You can see old items from Chinatown on the first floor of the Palm Street parking garage.
San Luis Obispo was a popular stop for travelers on U.S. Route 101 and California State Route 1. It was home to the first motel, the Milestone Mo-Tel.
One of San Luis Obispo's historic buildings is the former Carnegie Library at 696 Monterey Street. It was built in 1905 with money from Andrew Carnegie. The building served as the city library until 1955. Since 1956, it has been the San Luis Obispo County Historical Museum. This building is listed on the National Register of Historic Places.
