The Oldest House Museum Complex is owned and operated by the St. Augustine Historical Society. Visitors can experience an interactive guided tour of the Gonzalez-Alvarez House, a National Historic Landmark which is the oldest surviving Spanish colonial dwelling in St. Augustine.

While archaeological evidence exists that the site had been occupied since the 1600s, the present house dates to the early 1700s. Construction began around 1723 and it reached its final form in 1790, exhibiting Spanish and British Colonial architectural styles. The house reveals evidence of the First and Second Spanish periods, British, and American occupations.

Docents explain the daily lives of the settlers and foster discussions on building use, archaeology, lifestyle, and culture on the Florida frontier. Guests can experience a guided tour of Florida’s Oldest House, the history museum, ornamental gardens, a rotating exhibit gallery, and the museum store.
