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.

The Louisiana Governor's Mansion is the official residence of the governor of Louisiana and their family. The Governor's Mansion was built in 1963 when Jimmie Davis was Governor of Louisiana. The Mansion overlooks Capital Lake near the Louisiana State Capitol in Baton Rouge. The Mansion was designed by the architectural firm of Annan and Gilmer of Shreveport, Louisiana. The final construction cost for the building was $893,843.00. The inspiration for the exterior design was Oak Alley Plantation in Vacherie, Louisiana. Like many plantation homes built between 1830 and 1860, Oak Alley was designed with a second story veranda. The second-floor veranda found at Oak Alley was omitted. It was thought that the concept of a second story veranda was too informal for a Governor's Mansion. Although the new Mansion is in the Greek Revival style, it also incorporates several Georgian features such as dormers, a fanlight of the doorway at the front entrance, and the long window on the circular stairs in the rotunda. Inside, the floor plan includes twelve bedrooms and eighteen baths, two kitchens and one kitchenette, two dining rooms, one breakfast room, a receiving room for state affairs and another for routine business, a living room, a sitting room, two butleries and two security stations for the state troopers assigned to the mansion, and two offices-one for the governor and one for a secretary. Along with the dramatic spiral stairway in the rotunda, there is an elevator running from the basement to the third floor, as well as a system of dumbwaiters. These are wise amenities, considering the size of the house: altogether, the mansion comprises some twenty-five thousand square feet, serviced by a ninety-ton cooling system to battle Louisiana's oppressive summer weather. The main foyer at the mansion features a mural that depicts various aspects of Louisiana History as well as symbolic references to many past Louisiana Governors. This mural was originally painted in the year 2000 under the administration of Governor Mike Foster. It was most recently updated with symbolic references relating to Hurricane Katrina and then Governor Kathleen Blanco. White Doric columns line the building on three sides. The columns are interrupted on the east side by a driveway leading to an underground garage. The exterior of the building is constructed of hand-molded brick that has been painted white. The roof is made of cleft- face Vermont non-fading, gray-green slate. Front and side porches are of the same type of slate. Lamp posts located in the parking lot east of the building were once gas lights used in Plymouth, England. The cast iron railing atop the driveway retaining walls and at the second story windows was designed from the railing used on the old Beauregard House on Chartres Street in New Orleans and was modified with the diamond pattern by the architect. The mansion sits on an 8-acre (32,000 m2) parcel of land. The grounds include a tennis court, a swimming pool, a vegetable garden, and a fountain area. The Governor's Mansion is located at 1001 Capitol Access Road (LA-3045) in Baton Rouge, Louisiana 70802. The mansion is open to the public for tours by appointment only.
