Oxfordshire Artweeks is the UK’s oldest and biggest open studios and pop-up exhibition event, and the 38th festival, in the planning for spring 2020, promises to be brighter and bolder than ever before. Artists, potters, photographers, silversmiths, furniture-makers and more throw open doors across the county to welcome visitors, for free, into over 500 pop-up exhibitions at nearly 400 different locations throughout May (2nd-25th).
