Pentagon Barracks

State Field was the home stadium of the Louisiana State University Tigers football team prior to 1924. The field was built on the old downtown campus of LSU. It was located east of the Pentagon Barracks and at the site of the current Louisiana State Capitol Building. Prior to construction of State Field, football games were played on an area called the parade grounds which was located south of the Pentagon Barracks and west of Hill Memorial Library and George Peabody Hall. The field, known on the campus simply as the "athletic field", was later moved to a site with bleachers that was north of the campus' experimental garden, and next to the old armory building.

The Louisiana State Capitol (French: Capitole de l'État de Louisiane) is the seat of government for the U.S. state of Louisiana and is located in downtown Baton Rouge. The capitol houses the chambers for the Louisiana State Legislature, made up of the House of Representatives and the Senate, as well as the office of the Governor of Louisiana. At 450 feet (137 m) tall and with 34 stories, it is the tallest skyscraper in Baton Rouge, the seventh tallest building in Louisiana, and tallest capitol in the United States. It is located on a 27-acre (110,000 m2) tract, which includes the capitol gardens. The Louisiana State Capitol is often thought of as "Huey Long's monument" due to the influence of the former Governor and U.S. Senator in getting the capitol built. The building's construction was completed in 1931. It was listed on the National Register of Historic Places in 1978 and was designated a National Historic Landmark in 1982.

On September 8, 1935, United States senator and former Louisiana governor Huey Long was fatally shot at the Louisiana State Capitol in Baton Rouge, Louisiana. Long was an extremely popular and influential politician at the time, and his death eliminated a possible 1936 presidential bid against incumbent Franklin D. Roosevelt. Long was at the capitol to pass a redistricting bill to oust Judge Benjamin Henry Pavy, an opposition state judge. Shortly after passing the bill, Long was ambushed in a hallway by Carl Weiss, Pavy's son-in-law. According to the most widely accepted version of events, Weiss shot Long in the chest, and Long's bodyguards shot Weiss, killing him instantly. There remains some controversy over whether Weiss actually shot Long, with an alternative theory claiming he was shot by his bodyguard(s) by accident during the fight and another was that Weiss instead punched Long, who was then killed in the crossfire when his bodyguards opened fire on Weiss. Long was rushed to the Our Lady of the Lake Regional Medical Center, where emergency surgery failed to stop internal bleeding. He was pronounced dead at 4:10 a.m. on September 10, 31 hours after being shot. Over 200,000 people attended Long's funeral. His remains were buried on the grounds of the Louisiana State Capitol, which he had constructed. A statue of Long by Charles Keck was erected on his grave in 1940. Without Long as its leader, his Share Our Wealth movement collapsed, clearing the way for Roosevelt to be re-elected to the White House in a landslide. Long and Robert F. Kennedy of New York (in 1968) are the only two sitting United States senators to be assassinated.
