The built environment can seem harsh and uninviting, but we at Curious London take comfort from the things that true historians might regard as ephemeral or superfluous: a well-preserved shop sign, the staircase to a wartime shelter or the chance discovery of a Formica-clad caff.

So, if your heart beats that little bit faster at the sight of fading ghost signs or the lost floor tiles of a glamorous department store,

these handy illustrated guides are for you. Keep them, collect them, use one to inspire an amazing day out.
