The Louisiana State Capitol 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.
