The US National Arboretum is a 446-acre (180-hectare) expanse of forests, meadows, and gardens connected by 9 miles (14 kilometers) of roadways. Though most known for its diverse tree collection, the arboretum is also home to the National Bonsai Museum, National Herb Garden, and the 200-year-old U.S. Capitol columns.

The Basics

Congress established the National Arboretum in 1927 to breed and foster plants from different parts of the US. An advisory board, which included expert American landscape architect Frederick Law Olmstead, designed the arboretum to feature sculptures and other details alongside its collection of plants.

While the National Arboretum is free to visit, few tours include it on their itineraries, due in part to its large size. Private tours of 10 or more people can be booked through the arboretum’s website if reserved three weeks in advance.

Abandoned US Capitol Columns

The 22 Corinthian columns in Ellipse Meadow are easily mistakable for ancient Greek ruins, when, in fact, they were a part of the original 1828 US Capitol building. Forty years later, architects realized the columns were too weak to support the fully constructed dome, which was much larger than they had anticipated. After a long campaign to rescue the abandoned columns, the National Arboretum became their permanent home.
