This actually is marked on Google Maps, as Yaopaotai. Uncertain if the market is correct. However just read a travel post and the writer mentioned the right battery was demolished back in 1982 when they built the harbour there. Only the left battery was preserved. Both completion & demolition dates are only likely to be accurate to the year. No month and date could be verified.
