This free exhibition reveals what lies beneath Sydney's busiest train station
Long before Central Station opened in 1906 and became an essential hub for Sydney life, it was an essential hub for Sydney death. Thousands of commuters make their way through the station every day now, but in the decades following 1820 the site was one of the city's biggest burial grounds. When the cemetery closed in 1901, it was overgrown and there were more than 30,000 bodies buried there.
This exhibition at the State Library of NSW is a haunting look back in time to 19th century Sydney. It's experienced with a fascinating 35-minute audio track, telling the story of the site. You can listen on your own device, and it's recommended you bring your own headphones to get the best sound experience.
