Meigs oversaw construction of the new House and Senate chambers, as well as an innovative cast-iron dome, all initially designed by architect Thomas U. Walter. Taking full advantage of his authority, Meigs made critical engineering and design decisions, including selecting the artists (i.e., Italian fresco painter Constantino Brumidi, muralist Emanuel Leutze, and sculptors Thomas Crawford and Randolph Rogers) and subject matter for much of the Capitol's decoration and ornamentation.
