The Hammond-Harwood House is a five part Anglo-Palladian (derived from 16th Italian architect Andrea Palladio) mansion that features some of the best woodcarving and plasterwork in America. It maintains a kind of symmetry and system of proportions that are rarely seen in buildings of this period. While most 18th century structures were fashioned by amateurs and artisans, the Hammond-Harwood house was clearly the work of a trained professional architect. In addition to the architecture, the house features a wide variety of period decorative and fine arts.
The mission of the Hammond-Harwood House Association is to preserve, for public education and enjoyment, the architecturally significant Hammond-Harwood House museum and its collection of fine and decorative arts.
