United States Post Office and Courthouse (Los Angeles, California, 1910)

The Spring Street Courthouse, formerly the United States Court House in Downtown Los Angeles, is a Moderne style building that originally served as both a post office and a courthouse. The building was designed by Gilbert Stanley Underwood and Louis A. Simon, and construction was completed in 1940. It formerly housed federal courts but is now used by Los Angeles Superior Court. The United States Court House initially housed court facilities for the United States District Court for the Southern District of California, until the District was redrawn in 1966. It thereafter functioned as a court house with judges from the United States District Court for the Central District of California. There is another federal court house in the Roybal Building in Downtown Los Angeles. In February 2006, it was listed on the National Register of Historic Places as U.S. Court House and Post Office. It was designated a National Historic Landmark in 2012, as the site of Gonzalo Mendez et al v. Westminster School District of Orange County, et al, a major legal case in advancing the civil rights of Mexican-Americans, and a precursor to the landmark Brown v. Board of Education case.

The Bella Union Hotel in Los Angeles, California, constructed in 1835, is California Historical Landmark No. 656. It was effectively the last capitol building of Mexican California under Governor Pio Pico, in 1845–47, and was a center of social and political life for decades. The hotel was located at N. Main Street, on the east side, a few doors north of Commercial Street, which then ran east–west between Arcadia and Temple. The hotel was later known as the Clarendon and then as the St. Charles.

Fletcher Bowron Square is a public square in Los Angeles, in the U.S. state of California. The plaza is named after former mayor Fletcher Bowron and was dedicated in his honor in 1975. The sculpture Triforium is installed in the square.In 2017, the open space served as the end point for thousands of demonstrators who supported the impeachment of U.S. President Donald Trump.

Triforium is a 60-foot high, concrete public art sculpture mounted with 1,494 Venetian glass prisms, light bulbs, and an internal 79-bell carillon located at Fletcher Bowron Square in the Los Angeles Mall at Temple and Main streets in the Civic Center district of Downtown Los Angeles.

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.

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.

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. The building is also notable as the site of a 1971 bombing that killed an 18-year-old worker.

Don Abel Stearns House (El Palacio) was located in Los Angeles, California, US. His home was at the southeast corner of Main and Arcadia streets. Here he built a substantial, wide spreading adobe surrounding a large courtyard. The house was a one-story adobe, and covered the entire ground occupied by the block, with an extensive "patio" or inner court in the center. When the outer gates were closed, this was a citadel capable of withstanding a siege. The residence was on the site of what became the Baker Block; and it was for many years, both before and after the change of government, a prominent social center for Southern California. Abel Stearns was married to Arcadia Bandini de Stearns Baker, and it was at this home that the famously beautiful daughters of Don Juan Bandini (Arcadia, Josefa, and Ysidora) entertained their wide circle of acquaintances from San Diego and Santa Barbara at grand balls and other social functions characteristic of life in Spanish countries. Here Commodore Jones in 1842, and Captain Fremont in 1846 and 1847, and other distinguished historical figures at various periods were hospitably entertained.

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 Hall of Justice in Los Angeles is located at 211 W. Temple Street in the Civic Center district of Downtown Los Angeles. It occupies the southern two-thirds of the block between Temple and First streets and between Broadway and Spring streets. Built in 1925, it was together with Los Angeles City Hall were the first two large buildings opened in what would over the following decades demolish and transform the late-19th-century Central Business District to a Civic Center of modern landmark buildings and plazas. The Hall of Justice was designed in Beaux-Arts style by the Allied Architects Association, a coalition of Los Angeles-based architects founded in 1921 to design public buildings. Participating architects included Octavius Morgan, Reginald Davis Johnson, George Edwin Bergstrom, David C. Allison, Myron Hunt, Elmer Grey, Sumner Hunt and Sumner Spaulding.It was the centerpiece of the Los Angeles County justice system until it was damaged in the Northridge earthquake. It was the home of Los Angeles County courts, the Los Angeles County Coroner, the Los Angeles County Sheriff's Office, and the Los Angeles County District Attorney, and was for many years the primary Los Angeles County Jail. The Beaux-Arts 1925 building was featured on television shows including Dragnet, Perry Mason and Get Smart. It was also featured in Visiting... with Huell Howser Episode 1014.Notable residents of the Hall of Justice included Charles Manson, Sirhan Sirhan, and Shorty Rossi, star of the Animal Planet show Pit Boss. Autopsies performed at the Hall of Justice include those of actress Marilyn Monroe and the assassinated presidential candidate and former United States Attorney General Robert F. Kennedy. It was used as a filming location for the 1997 Clint Eastwood movie Absolute Power, as the Washington, D.C. police headquarters.The Hall of Justice was shut down after January 1994 after sustaining damage because of the 1994 Northridge earthquake. In 2015, the building re-opened after undergoing a complete restoration and seismic retrofitting. The restoration and retrofit of the building was performed by the design build team consisting of Clark Construction, AC Martin Architects, and Englekirk Structural Engineers. The offices of the Los Angeles County Sheriff and the District Attorney returned to the building with its reopening.
