De Vargas Street House

The De Vargas Street House, often referred to as the Oldest House, is a historic building in Santa Fe, New Mexico, which is often said to be one of the oldest buildings in United States. The original date of construction is unknown but the majority of the building is believed to date to the Spanish colonial period (post-1610). One archaeological study also concluded that some sections of the walls are characteristic of Pueblo architecture and may be pre-Spanish in origin. The building was listed on the National Register of Historic Places and New Mexico State Register of Cultural Properties in 1968 as a contributing property in the Barrio De Analco Historic District.
