U.S. National Arboretum
3 Things to Look For: (1) Straight ahead: The National Capitol Columns, 22 Corinthian columns built as part of U.S. Capitol’s east portico in 1828 and remained there until 1958; (2) to the left: the National Herb Garden, the largest designed herb garden in the country; (3) directly behind: the National Arboretum’s Ellipse Meadow.
