The Griffin Estate is one of St. Augustine's oldest surviving residences, located in the historic Lincolnville neighborhood. Originally constructed from coquina stone between 1760 and 1790, the building likely served as a colonial guard house overlooking the San Sebastian River. In 1838, the property was named "Yallaha," a Seminole word meaning "orange," reflecting its once-thriving 14-acre orange grove. After decades of decline and hurricane damage, the property was restored in 2021 by Joe and Tammy Griffin. Today, the Griffin Estate stands as a nationally certified historic structure and a symbol of St. Augustine's layered past.
