Galt Cottage is a one-and-a-half-story frame structure that was originally located behind the public hospital in Williamsburg, Virginia. The house started out as a single-roomed hall house with a chimney heating the first and second floors, which was later extended on three sides to form the present building. It was moved twice in the twentieth century, first to Duke of Gloucester Street in 1929 and then to Tyler Street in the 1950s.

Dendrochronological analysis has shown that one of the timbers from the primary phase of the structure was felled in the winter of 1809/10 and that three of the timbers from the secondary phase were felled in the winter of 1811/12 and the spring of 1812. A single timber sampled as part of the secondary phase was found to have a felling date of the winter of 1830/31, suggesting that this timber was inserted as a later repair to the secondary phase basement ceiling.
