The City and Borough of Juneau, is the capital city of Alaska. It is a unified municipality located on the Gastineau Channel in the Alaskan panhandle, and it is the second largest city in the United States by area. Juneau has been the capital of Alaska since 1906, when the government of what was then the District of Alaska was moved from Sitka as dictated by the U.S. Congress in 1900. The municipality unified on July 1, 1970, when the city of Juneau merged with the city of Douglas and the surrounding Greater Juneau Borough to form the current municipality, which is larger by area than both Rhode Island and Delaware.
The Alaska State Capitol in downtown Juneau was originally built as the Federal and Territorial Building in 1931. Prior to statehood, it housed federal government offices, the federal courthouse and a post office. It also housed the territorial legislature and many other territorial offices, including that of the governor. Today, Juneau remains the home of the state legislature and the offices of the governor and lieutenant governor. Some other executive branch offices have moved elsewhere in the state.
The Juneau area is in a transition zone between a continental climate, and an oceanic climate, depending on the isotherm used. The city is milder in winter than its latitude may suggest, due to the influence of the Pacific Ocean. Winters are moist and long and spring, summer, and fall are cool to mild, with highs peaking in July at 18.3 °C.
