Metropolitan Detention Center, Los Angeles

Yaanga was a large Tongva (or Kizh) village originally located near what is now downtown Los Angeles, just west of the Los Angeles River and beneath U.S. Route 101. People from the village were recorded as Yabit in missionary records although were known as Yaangavit, Yavitam, or Yavitem among the people. It is unclear what the exact population of Yaanga was prior to colonization, although it was recorded as the largest and most influential village in the region. Yaangavit were used as slave laborers during the Mission period by Franciscan padres to construct and work at San Gabriel Mission and Nuestra Señora Reina de los Ángeles Asistencia and forced laborers for the Spanish, Mexican, and American settlers to construct and expand Los Angeles. The colonizers' dependency on Yaanga for forced labor is thought to be a reason for its ability to survive longer than most Indigenous villages in the region. However, after the founding of Pueblo de Los Ángeles in 1781, Yaanga increasingly "began to look more like a refugee camp than a traditional community," and following relentless pressure on the inhabitants to assimilate, the community was eventually dispersed.The original village seems to have only remained intact until about 1813. After being forcibly relocated several times, eventually eastward across the Los Angeles River, it was razed to the ground by the Los Angeles City Council under American occupation in 1847. Buried intact deposits from Yaanga have been found throughout downtown Los Angeles, such as in the vicinity of Alameda Street, Bella Union Hotel, Union Station, Plaza Church, and the Metropolitan Water District Headquarters.

The New World is a sculpture by Tom Otterness, installed outside Los Angeles' Edward R. Roybal Federal Building, in the U.S. state of California.

The Edward R. Roybal Federal Building and United States Courthouse is a United States federal courthouse of the United States District Court for the Central District of California, in the Civic Center district of Los Angeles, California. It is located on Temple Street in Downtown Los Angeles, east of and adjacent to the Federal Building at 300 N. Los Angeles Street, architect Welton Becket, opened in 1965. The building was completed in January 1992 and is named for long-serving United States Congressman Edward R. Roybal. In the year after its completion, 1993, it gained publicity as the site of the federal trial of the four Los Angeles Police Department officers who were charged in 1991's Rodney King video beating; the trial being held the year after their acquittals in state court in Simi Valley. Prior to the opening of the building, some controversy was stirred by the removal of a statue of a nude by sculptor Tom Otterness, which Roybal had objected to as appropriate for a museum but not for a federal building.

On January 28, 1971, at 4:30 p.m. PST, an explosion in the second-floor men's room of the 300 North Los Angeles Street federal building in California, United States, killed 18-year-old employee Tomas Ortiz, a resident of City Terrace. Ortiz was a student at L.A. Trade Tech, and a part-time employee of the General Services Administration, assigned to the Internal Revenue Service. News accounts variously described him as a "janitor" and a "mail orderly."Ortiz's right leg was blown off below the knee, and his left leg was partially severed. He also suffered "severe head injuries," and died en route to the hospital. The coroner declared his cause of death was a combination of skull fractures, brain lacerations, and blood loss from the leg injuries.The bomb ripped a 4 ft (1.2 m) by 5 ft (1.5 m) hole through the wall. The blast was powerful enough to shatter the washbasins in the bathroom and damage the washrooms on the floors above and below the bomb site. Water lines and electric circuits were also broken.The morning after the explosion, the Los Angeles Times reported, "An investigation was underway to see if Ortiz was involved in placing the bomb in the building. The federal building has been under tight security for several months because of a series of bombings of public buildings. Guards use metal detectors at the entrances, and packages are searched." However, people not carrying packages were not searched, and a second and third entrance had little or no security controls. On Sunday, law enforcement told the L.A. Times that there was no obvious "militancy" in Ortiz's background and "absolutely no evidence" that he was involved in planting the bomb.In April 1971, Los Angeles Mayor Sam Yorty suggested that there was a connection between the federal building bomb and a Chicano Moratorium march that had occurred the same weekend. At the time of the 1974 LAX bombing it was noted that the FBI had not identified any suspects in the 1971 federal building bombing and the case remained open.Historians generally attribute the bombing to the Chicano Liberation Front, which claimed responsibility for a series of bombings in the Los Angeles area in 1970 and 1971. Ortiz's death was described as "obviously accidental" in the Los Angeles Free Press in 1971 and "accidental and unintended" in a 2000 review of patterns in American domestic terrorism. The CLF never claimed responsibility for nor commented upon the federal building bomb; if it was CLF, Ortiz was the only fatality—indeed the only casualty of any kind—as a consequence of their bombing spree. Tomas "Tommy" Ortiz was born September 17, 1952, in El Paso, Texas. He lived with his parents on Volney Drive, and was a graduate of Roosevelt High School. He was buried at Rose Hills Memorial Park in Whittier, California.

The Metropolitan Water District of Southern California is a regional wholesaler and the largest supplier of treated water in the United States. The name is usually shortened to "Met," "Metropolitan," or "MWD." It is a cooperative of fourteen cities, eleven municipal water districts, and one county water authority, that provides water to 19 million people in a 5,200-square-mile (13,000 km2) service area. It was created by an act of the California Legislature in 1928, primarily to build and operate the Colorado River Aqueduct. Metropolitan became the first (and largest) contractor to the State Water Project in 1960. Metropolitan owns and operates an extensive range of capital facilities including the Colorado River Aqueduct which runs from an intake at Lake Havasu on the California-Arizona border to its endpoint at the Lake Mathews reservoir in Riverside County. It also imports water supplies from northern California via the 444-mile (715 km) California Aqueduct as a contractor to the State Water Project. In 1960, Metropolitan became the first (and largest) contractor to the State Water Project. Metropolitan's extensive water system includes three major reservoirs, six smaller reservoirs, 830 miles (1,340 km) of large-scale pipes, about 400 connections to member agencies, 16 hydroelectric facilities and five water treatment plants. It serves parts of Los Angeles, Orange, San Diego, Riverside, San Bernardino and Ventura counties. The district covers the coastal and most heavily populated portions of Southern California; however large portions of San Diego, San Bernardino and Riverside counties are located outside of its service area. The Metropolitan headquarters is in downtown Los Angeles, adjacent to historic Union Station.

Boring [the City paid him $160.75 for his drawings], and built in 1884, it operated as a firehouse until 1897. The building was thereafter used as a saloon, cigar store, poolroom, "seedy hotel", Chinese market, "flop house", and drugstore. The building was restored in the 1950s and opened as a firefighting museum in 1960. The Plaza Firehouse Museum is open to the public Tuesdays through Sundays from 10 a.m. to 3 p.m. The museum features helmets, photos, and firefighting equipment of the late 19th and early 20th centuries.

The Los Angeles Mall is a small shopping center and series of plazas (public squares) at the Los Angeles Civic Center, between Main and Los Angeles Streets on the north and south sides of Temple Street, connected by both a pedestrian bridge and a tunnel. It features Joseph Young's sculpture Triforium, a colorful sculpture unveiled in 1975, which has 1,500 blown-glass prisms synchronized to an electronic glass bell carillon. The mall opened in 1974 and includes a four-level parking garage with 2,400 spaces. It stands on the site of what once was some of the oldest commercial blocks in the city that was demolished in the 1940s and 1950s. The mall was designed by the architectural firm Stanton & Stockwell, which also designed the Los Angeles County Courthouse and Kenneth Hahn L.A. County Hall of Administration. It was conceived as a "town square" for meetings, retail, public institutions, and public art, serving the general public and the tens of thousands of government employees working at the Civic Center's municipal, state, and federal buildings. Cornell, Bridgers, Troller and Hazlett were the landscape designers.

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.
