So you think you know England’s cities? Scratch the surface and you’ll be surprised at what’s revealed. Quirky vintage shops, hidden artists’ studios, guided strolls through secret streets on the trail of little-known local legends. Hushed-up treasures can be found cradled in miniscule museums and tours go beneath the pavements for an insight into a hidden subterranean world. We turn the spotlight away from the obvious and get under the skin of our urban favourites on cool city breaks. But shh, keep it to yourself.
