Sitting above a factory, wonderfully illuminated by skylights, Gage is run by Kelham Island Art Collective (KIAC). As well as putting shows by its members, who include painters, sculptors, stone carvers and textile artists, it's hosted exhibitions by local artists and even the likes of Arctic Monkeys.
Look out for Open Up Sheffield dates, usually in May, to get a look at the KIAC studios next door, or head to the education space for life drawing and sculpture classes – see the website for upcoming dates.
