Manchester Central Convention Complex (commonly known as Manchester Central or GMEX (Greater Manchester Exhibition Centre)) is an exhibition and conference centre converted from the former Manchester Central railway station in Manchester, England. The building has a distinctive arched roof with a 64-metre span – the second-largest railway station roof span in the United Kingdom, and was granted Grade II* listed building status in 1963. In 2020, the complex became a temporary field hospital for non-critical coronavirus patients, part of a network of temporary NHS Nightingale Hospitals.
