About Jefferson Patterson Park & Museum

Many of its buildings were designed by Gertrude Sawyer starting in the 1930s, and some landscaping was done by Rose Greely and Cary Millholland Parker. The property has more than 70 identified archaeological sites, with current excavation and research being done. The land features 9,000 years of documented human occupation.
