The Udderbelly can be used for a variety of different purposes as it can be adapted to contain a stage and all-seater 405 seat venue, or alternatively can be completely empty inside. The exterior skin can either be the upside-down purple cow, or alternatively a white, silver, or purple tent. The tent has an aluminum truss frame that is designed to be strong enough to carry several tonnes of weight in lighting and sound equipment.
It was first unveiled for the 2006 Edinburgh Festival Fringe and was situated in Bristo Square (which itself was converted into a large outdoor pub known as The Pasture). It also appeared in Brighton's Old Steine for the 2007 and 2008 Brighton Festival Fringe. It has since been a permanent event in the Edinburgh Fringe.
On its return to the Brighton Fringe in 2008 it brought with it a smaller adjoining venue known as the Udder Place.
