York: an emperor, a Viking king and a tower that turned pink

York grew from a Roman fortress into a Viking capital and a medieval city of churches and crafts, and many of its stories still hide in its lanes, gateways and windows. This quiz invites you to discover them in 20 questions with pictures.

What did the Roman name of the city probably mean, and what does the ending of so many of its lane names really mean? Who was proclaimed emperor by the soldiers here in 306, which king drove out the last Viking ruler, and why did a helmet found in a Viking-age dig surprise everyone?

Then the Minster and the castle: what story fills the window above the high altar, whom does a grey window of five lancets remember, and who set the choir alight in 1829? Why is the stone of the keep on its mound faintly pink, and what happened there in March 1190? Which craft gave the Shambles its name, why did Margaret Clitherow refuse to plead, what was once shown on top of Micklegate Bar and what makes Walmgate Bar unique?

There are also questions on an innovation of 1367 on Ouse Bridge, on why the Corpus Christi plays were called «mystery» plays, on Dick Turpin's ride, on a school's Bonfire Night custom, on the first trains inside the walls and on how a sweet shop near Bootham Bar began. The pictures are old photographs, photochroms, engravings, paintings, watercolours and drawings in the public domain.
