The Nicholas Carriger Estate (16-acre) is a collection of buildings located in Sonoma, California, United States. The estate consists of three buildings: the main house built in 1847, a small house, which is a replica of the main house, built in 1860, and a winery, built in 1875. The main house and the Little Carriger house fall in the architectural Greek revival style. There also is a locally quarried "candy rock" stone small building next to the main house that may have been used as an ice house. The everflowing Yulupa Spring, which supplied water to the houses and is still flowing, is a short walk along a hillside pathway from the main house. In 1979 the estate was designated a Sonoma County Historic Landmark, and in 2001, it was added to the National Register of Historic Places.
