Hobart Town Hall Underground is a group of intimate former civic rooms beneath the historic Town Hall at 7 Elizabeth Street. City of Hobart describes a passage and four cave-like rooms, with dimensions ranging from about 3 by 7.7 metres to 7.2 by 7.7 metres, lighting and electrical outlets. The textured heritage interior makes an atmospheric setting for installations, contemporary music, sculpture, performance art, small exhibitions and book launches. It is not a single convention hall and council does not give a verified combined guest capacity on its venue page. Access needs and technical setup should be confirmed before booking.
