The Los Angeles Chinese massacre of 1871 was a racial massacre targeting Chinese immigrants in Los Angeles, California, United States that occurred on October 24, 1871. Approximately 500 white and Hispanic Americans attacked, harassed, robbed, and murdered the ethnic Chinese residents of the old Chinatown neighborhood of the city of Los Angeles, California. The massacre took place on Calle de los Negros, also referred to as "Negro Alley". The mob gathered after hearing that a policeman and a rancher had been killed as a result of a conflict between rival tongs, the Nin Yung, and Hong Chow. As news of their death spread across the city, fueling rumors that the Chinese community "were killing whites wholesale", more men gathered around the boundaries of Negro Alley. A few 21st-century sources have described this as the largest mass lynching in American history.Nineteen Chinese immigrants were killed, fifteen of whom were later hanged by the mob in the course of the riot, but most of whom had already been shot to death before being hanged. At least one was mutilated, when a member of the mob cut off a finger to obtain the victim's diamond ring. Those killed represented over 10% of the small Chinese population of Los Angeles at the time, which numbered 172 prior to the massacre. Ten men of the mob were prosecuted and eight were convicted of manslaughter in these deaths. The convictions were overturned on appeal due to technicalities.

Los Angeles Plaza or Plaza de Los Ángeles is located in Los Angeles, California. It is the central point of the Los Angeles Plaza Historic District. When Governor Felipe de Neve founded the Pueblo de Los Ángeles, his first act was to locate a plaza for the geographical center from which his town should radiate. De Neve's plaza was rectangular in form—75 varas wide by 100 in length. It was located north of the church; its southerly line very nearly coincided with the northerly line of West Marchessault street. On this, the cuartel (guard house), the public granary, the government house and the capilla (chapel), fronted.It is located just north of the original village site of Yaanga, which was used as a reference point in the construction of the plaza.

El Pueblo de Los Ángeles Historical Monument, also known as Los Angeles Plaza Historic District and formerly known as El Pueblo de Los Ángeles State Historic Park, is a historic district taking in the oldest section of Los Angeles, known for many years as El Pueblo de Nuestra Señora la Reina de los Ángeles del Río de Porciúncula. The district, centered on the old plaza, was the city's center under Spanish (1781–1821), Mexican (1821–1847), and United States (after 1847) rule through most of the 19th century. The 44-acre park area was designated a state historic monument in 1953 and listed on the National Register of Historic Places in 1972.

The Italian American Museum of Los Angeles (Italian: "Museo Italo Americano di Los Angeles" and abbreviated IAMLA) is a museum located in downtown Los Angeles, California, and is part of the El Pueblo de Los Ángeles Historical Monument.

The museum opened in 2016 and has presented historical exhibits on Italians in Los Angeles, including Sunshine and Struggle and a variety of educational and cultural events.

The Ávila Adobe, built in 1818 by Francisco Ávila, is the oldest standing residence in the city of Los Angeles, California. Avila Adobe is located in the paseo of historic Olvera Street, a part of the Los Angeles Plaza Historic District, a California State Historic Park. The building itself is registered as California Historical Landmark #145, while the entire historic district is both listed on the National Register of Historic Places and as a Los Angeles Historic-Cultural Monument. The Plaza is the third location of the original Spanish settlement El Pueblo de Nuestra Señora la Reina de Los Ángeles sobre el Río Porciúncula, the first two having been washed out by flooding from the swollen Río Porciúncula (Los Angeles River). The Avila Adobe was one of the settlement's first houses to share street frontage in the Pueblo de Los Angeles of Spanish colonial Alta California. The walls of the Avila Adobe are 2.5–3 feet (0.76–0.91 m) thick and are built from sun-baked adobe bricks. The original ceilings were 15 feet (4.6 m) high and supported by beams of cottonwood, which was available along the banks of the Los Angeles River. Though the roof appears slanted today, the original roof was flat. Tar (Spanish: brea) was brought up from the La Brea Tar Pits, located near the north boundary line of Avila's Rancho Las Cienegas. The tar was mixed with rocks and horsehair, a common binder in exterior building material, and applied to beams of the roof as a sealant from inclement weather. The original floor of the Avila adobe was hard-as-concrete compacted earth, which was swept several times a day to keep the surface smooth and free from loose soil. (Dirt floors were common among most early adobes.) In later years, varnished wood planks were used as flooring. The original structure was nearly twice as long as it now appears and was "L"-shaped, with a wing that extended nearly to the center of Olvera Street. The rear of the house had a long porch facing the patio. Francisco tended a garden and a vineyard in the rear courtyard. The nearby Zanja Madre (literally "Mother Ditch") was a main water aqueduct and irrigation ditch that brought water down to the Pueblo from the Los Angeles River and was close enough to the adobe for Francisco Avila to avail himself. Avila eventually added a wooden veranda and steps to the front of the adobe.

The Lugo Adobe also called the Vicente Lugo Adobe or Casa de Don Vicente Lugo was a house in the City of Los Angeles, located on the east side of the Los Angeles Plaza at 512–524 N. Los Angeles Street.Don Vicente Lugo built the home in what is now called the El Pueblo de Los Ángeles Historical Monument in the 1840s. The Lugo Adobe was designated a California Historic Landmark (No.301) on July 12, 1939. Lugo Adobe was one of the very few two-story homes in the Pueblo of Los Angeles. In 1867 Don Vicente Lugo donated the Adobe to St. Vincent's School, that later became Loyola Marymount University. St. Vincent's School used the building for two years before moving the School. The building became part of what is now called Old Chinatown Los Angeles. When Old Chinatown became run down, Los Angeles put into place a redevelopment plan. The California Historic Landmark given to the Lugo Adobe did not save the Adobe from redevelopment. The Lugo Adobe was demolished in 1951, despite significant efforts to save it.The site of the former Lugo Adobe is now Father Junípero Serra Park on the east side of the Los Angeles Plaza and the east side of N. Los Angeles Street, just west of Union Station and just east of the southern end of Olvera Street.

A statue of Junípero Serra (sometimes called Father Junipero Serra or Fra Junipero Serra) was installed in a portion of El Pueblo de Los Ángeles Historical Monument informally known as Father Serra Park in Los Angeles, California.

Olvera Street (also Calle Olvera or Placita Olvera, originally Calle de los Vignes, Vine Street, and Wine Street) is a historic street in downtown Los Angeles, and a part of El Pueblo de Los Angeles Historic Monument, the area immediately around the 19th-century Los Angeles Plaza, which has been the main square of the city since the early 1820s, when California was still part of Mexico, and was the center of community life until the town expanded in the 1870s. Many of the Plaza District's historic buildings are on Olvera Street, including its oldest one, the Avila Adobe, built in 1818; the Pelanconi House built in 1857; and the Sepulveda House built in 1887. Restaurants, vendors, and public establishments are along the pedestrian mall, a block-long narrow, tree-shaded, brick-lined marketplace where some merchants are descended from the original vendors who opened shops when a then-decrepit Olvera Street was recreated as a tourist attraction in 1930, a romanticized version with the theme of a Mexican marketplace. The exterior facades of the brick buildings enclosing Olvera Street and on the small vendor stands lining its center are colorful piñatas, hanging puppets in white peasant garb, Mexican pottery, serapes, mounted bull horns, and oversized sombreros. Olvera Street attracts almost two million visitors per year who can find, while not an authentic Mexican or Mexican-American market, an homage to the history and traditions of the pueblo's early settlers and the city's Mexican heritage.

The Plaza Substation was an electrical substation that formed a part of the "Yellow Car" streetcar system operated by the Los Angeles Railway from the early 1900s until 1963. After being threatened with demolition in the 1970s, the Plaza Substation was added to the National Register of Historic Places in 1978.
