The United States Capitol, often called The Capitol or the Capitol Building, is the meeting place of the United States Congress and the seat of the legislative branch of the U.S. federal government. It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. Though no longer at the geographic center of the federal district, the Capitol forms the origin point for the district's street-numbering system and the district's four quadrants. The original building was completed in 1800. It was partly destroyed in the 1814 burning of Washington, then was fully restored within five years.
The Reichstag (German: Reichstagsgebäude pronounced [??a?çsta?ksg??b??d?]; officially: Deutscher Bundestag -- Plenarbereich Reichstagsgebäude pronounced [ ?d??t?? ?b?nd?s?ta?k ?ple?na?rb?ra?ç ??a?çsta?ksg??b??d?]) is a historic edifice in Berlin, Germany, built to house the Imperial Diet (German: Reichstag) of the German Empire. It was opened in 1894 and housed the Diet until 1933, when it was severely damaged after being set on fire. Following World War II, the building fell into disuse; the parliament of the German Democratic Republic (the Volkskammer) fulfilled in the Palast der Republik in East Berlin, while the parliament of the Federal Republic of Germany (the Bundestag) fulfilled in the Bundeshaus in Bonn. The destroyed building was made secure against the elements and partly refurbished in the 1960s, but no attempt at full restoration was made until after German reunification on 3 October 1990, when it underwent a reconstruction led by architect Norman Foster. Following its completion in 1999, it once more became the meeting place of the German parliament: the modern Bundestag. The expression Reichstag, when used to connote a diet, dates back to the Holy Roman Empire. The building was built for the Diet of the German Empire, which was succeeded by the Reichstag of the Weimar Republic. The latter would become the Reichstag of Nazi Germany, which left the building (and ceased to function as a parliament) after the 1933 fire and never returned, using the Kroll Opera House rather; the term Reichstag hasn't been used by German parliaments since World War II. In today's usage, the term Reichstag (Imperial Diet) refers mainly to the construction, while Bundestag (Federal Diet) identifies the institution.Source: Wikipedia
