Published the year that the 1824 Capitol dome was taken down, this print shows the appearance of the Thomas U. Walter plan for the extended Capitol building and dome, approved in 1854. The new north and south wings of the building pictured here opened in the following few years, though the dome remained under construction until after the outbreak of the Civil War.
