thumb|From the 1860s until the 1930s, the court sat in the Old Senate Chamber of the U.S. Capitol. The Supreme Court first met on February 1, 1790, at the Merchants' Exchange Building in New York City. When Philadelphia became the capital, the court met briefly in Independence Hall before settling in Old City Hall from 1791 until 1800. After the government moved to Washington, D.C., the court occupied various spaces in the Capitol building until 1935, when it moved into its own purpose-built home. The four-story building was designed by Cass Gilbert in a classical style sympathetic to the surrounding buildings of the Capitol and Library of Congress, and is clad in marble. The building includes the courtroom, justices' chambers, an extensive law library, various meeting spaces, and auxiliary services including a gymnasium. The Supreme Court building is within the ambit of the Architect of the Capitol, but maintains its own Supreme Court Police, separate from the Capitol Police.
