It is not a space without its challenges - there are areas that get wet when it rains, or they water the grass in the Memorial Gardens above, it's unheated so it can get cold, you can't fix anything to walls or ceiling and it has no natural light or lighting system.
But is bang smack in the city centre in an area just behind the market that get a huge footfall as pedestrians pass by and criss cross from Jarrolds to the Forum and St Giles to Gentlemans Walk. The market attracts hundreds of people everyday for Reggie's teastall or the chip and mushy peas stall. So it is a fine place to run an exhibition that can be free and easy to access.
In a couple or weeks, Norwich Fringe Festival will move in with work by Nick Ball, Samia Malik, Roger Eno, Sweet Arts, Moosey Art, Shhhh Collective and Parallel Point, Theo Fenning, Andrew Logie and Tracey Tutt.
As well as visual art, there will be a programme of performance and workshops including the Fringe Twilight Hour 6-7pm most days when there will be something 'popping up' in the Undercroft space.
Access is via a large wooden door down a short flight of steps opposite the Guildhall.
The Undercroft is available to hire from Norwich City Council for the cost of paying the rates - contact firstname.lastname@example.org
