Lincoln is the capital city of Nebraska, located about one hour southwest of Omaha. The state capitol building in Lincoln is very unique. It is tall and has a domed tower at the top with multiple observation decks. However, the place you won't want to miss while in Lincoln is the Sunken Gardens. This public garden was constructed in 1931 in an area that used to be a neighborhood junkyard. Today this beautiful garden attracts tourists from all over the country.
