There's a mapping exhibition at Bury Art Gallery at the moment. To quote the blurb....

This exhibition investigates the whole process of "mapping" and shows how contemporary artists have abstracted and expanded it into art. The show allows the visitor to explore not just maps of geographical territory but also "maps" that are essentially schematizations of thought processes embracing many other disciplines such as history and philosophy.

The exhibition highlights how artists have used and interpreted maps and explored the many different systems of mapping. The show includes a great variety of forms from cartographic both historic and contemporary maps, to mind maps and other diagrammatic systems.
Have not been myself & they're closed Sunday's & Bank Hols so may struggle to do so.
