In this museum – otherwise known as a shuttered regional hospital – a special room is dedicated to the science of deterioration. Enter this glass-framed exhibition space and you can admire an astonishing specimen of wall decomposition with its characteristic folds of drooping paint. Stay as long as you like, the show will only get better. There is even a bench for those who would like to sit and sketch or simply contemplate the epidermal changes in the scenery. All that’s missing are a few informative plaques. We’ll be sure to bring them the next time we come.
