A failed circus gave birth to the eventual Zoo Atlanta when local lumber merchant George Gress purchased animals from the circus and donated them to the city in 1889. The city decided Grant Park was the best location for the zoo and carved space out for the attraction. Later zoo expansions and parking requirements caused the removal of a portion of the lake. In 1892, the circular painting of the Battle of Atlanta was exhibited in the park. The cyclorama would eventually gain its own dedicated building in the park in 1921. Near the zoo is the Erskine Memorial Fountain, Atlanta's first public fountain, which was built in 1896 and moved to Grant Park in 1912. In 1948, another park landmark, the Thomas W. Talbot Monument, was dedicated by members of the International Association of Machinists, honoring their founder, Thomas W. Talbot.
