A Private Gift Created Public Art
The National Gallery of Art was not built by the government, but by a single wealthy donor. Andrew W. Mellon donated his massive personal collection and the money to build the museum for the American public.
While it stands as a national monument, the gallery began as a private philanthropic venture. Mellon provided the core collection and the funding to construct the building, turning his private passion into a public institution. It remains completely free to visit today, upholding his vision of accessibility. It is rare for such a significant government site to have originated from one individual's private wealth and initiative.
