Edward R. Roybal Federal Building and United States Courthouse

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.

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 300 North Los Angeles Street Federal Building, located across the street from the Edward R. Roybal Federal Building and United States Courthouse, is a federal building of the United States that opened in 1965 and is now on the National Register of Historic Places.

Bell Block (originally, “Bell’s Row”) was a building in Los Angeles in the U.S. state of California. Situated on the corner of Aliso and Los Angeles streets, it was built in 1845 by Captain Alexander Bell. It was one of the few two-story adobe buildings in the then one-story adobe town of 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.

Los Angeles Street, originally known as Calle de los Negros or Alley of the Black People, is a major thoroughfare in Downtown Los Angeles, California, dating back to the origins of the city as the Pueblo de Los Ángeles.

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.

Parker Center, initially named the Police Administration Building or Police Facilities Building, was the former headquarters of the Los Angeles Police Department from 1955 until October 2009. It was located in Downtown Los Angeles at 150 North Los Angeles Street. Often nicknamed "The Glass House", the building was named for former LAPD chief William H. Parker in 1966.The LAPD moved to a different headquarters building in 2009 after the Parker Center became outdated. After the building was shifted to mostly secondary use, and attempts to preserve the building failed, the Los Angeles Bureau of Engineering recommended its demolition. Demolition and razing of the Parker Center was approved in 2017, and completed in 2019. Plans to replace the building with the Los Angeles Street Civic Building were scrapped in 2020 due to a lack of funds.
