Below is the Gesner Mansion (also known as the Georgetown Castle), which I sketched the first year. The home owner bought that sketch and it's now displayed inside on a wall with other paintings of the home by local artists.
This home was built in 1893 and belonged to the Mayor of Georgetown (before it became part of Seattle).
