Businesses on the corner of Sixth and Island Circa 1970. Zuniga Wholesale Produce at 509 Sixth was demolished to make room for condominiums, but San Diego's oldest bar, Tivoli, established in 1885, is still operating at 505 Sixth. Abraham Klauber and Samuel Steiner recorded the deed from Alonzo Horton in 1869 for the lots on the southwest corner for Klauber Warehouse. It is now the site of Ballpark Self Storage, but part of Klauber Wangenheim Company's building remains.
