United States Capitol
The capitol has a large dome in the center, above a rotunda—a large space that is shaped like a circle.   There are two wings that are connected to the rotunda on opposite sides. The north wing is where the Senate meets and the south wing is where the House of Representatives meets.  These wings are also called chambers.  On the top floors of the chambers are galleries'', or balconies where people can watch the Senate and House of Representatives from above.
