Jefferson Square is a park containing an Athletic Field located at 7th St & Martin Luther King. (Strangely the location imported from the City has it at 7th Avenue and Grove. Grove is now MLK and the park is at 7th Street, not 7th Avenue).
On December 20, 1983, Jefferson Square was designated an Oakland Landmark #LM83 -398.
