U.S. National Arboretum - National Capitol Columns

The U.S. National Arboretum was established by Congress in 1927 and serves as a living museum of trees, shrubs, and collections for research and public education. A prominent feature is the National Capitol Columns: 22 Corinthian columns removed from the U.S. Capitol East Portico and re-erected on a hill at the arboretum as a landmark display. The arboretum encompasses ornamental gardens, trial gardens, and scientifically curated plant collections.
