Overview & visitor information
The dome that anchors Boston's skyline postcards is real 23-karat gold leaf, crowning the 1798 State House designed by Charles Bulfinch - the building that made him America's defining capitol architect. Free guided tours run on weekdays (reservations advised; verify current scheduling), walking visitors through the marble Hall of Flags, the House chamber beneath its Sacred Cod - a carved fish hung as a maritime talisman since colonial times - and murals of Massachusetts history. It is a working seat of government, so security screening applies and sessions occasionally close rooms. The exterior alone justifies the Beacon Hill photo stop where the Freedom Trail passes the gates; the interior adds substance for civics-curious teenagers. Twenty exterior minutes or a one-hour tour, then Acorn Street's lanterns wait two blocks behind.
