Apparently that was never built. The article you linked mentions the “old Central Park site” at 8th and Market. According to http://www.sfcityguides.org/public_guidelines.html?article=369&submitted=TRUE&srch_text=&submitted2=&topic=Buildings%20and%20Theaters
“The four-acre lot at Market and Eighth had hosted crowds well before the Crystal Palace Market was built there. From 1874 to 1881, it was the site of the Mechanics Institute Pavilion where annual mechanics’ and manufacturers’ fairs were held. After that pavilion was demolished in 1881, the California Baseball League got its start at Central Park built on the lot. Shortly before the turn of the century, when the league outgrew the site, the park was replaced by the Central Theater, featuring touring shows and melodramas. It was destroyed in 1906, and for the next 16 years the empty “Circus Lot” hosted Ringling Brothers, Barnum & Bailey, and all the other big circuses and carnivals, plus a balloon ascension attraction.
“In 1922, brothers Oliver and Arthur Rosseau bought the four-acre site and started their fabulous bazaar. Emporium-Capwell purchased it and the adjoining property in 1925; then in 1944 it was bought by 33-year-old Joseph Long of Alameda, who in the previous seven years had started a chain of drug stores. He “modernized” the huge market by breaking up its open spaces and building a large drugstore in one corner. But postwar tastes changed as families moved out to the suburbs. On August 1, 1959, the Crystal Palace Market closed its doors and was demolished to make room for the new $8 million, 400-room Del Webb TowneHouse luxury motel.”
