The Capitol houses the Louisiana State Legislature, the governor's office, and parts of the executive branch. At 450 feet (137 meters) tall, with 34 stories, it is the tallest capitol building in the United States, the tallest building in Baton Rouge, and the seventh-tallest building in Louisiana. It is located on a 27-acre (110,000 m2) tract, which includes the capitol gardens. Huey P. Long championed the project as governor and was later shot by an assassin in the building. He is buried in the Capitol gardens. The Louisiana State Capitol building is a National Historic Landmark.
