Cheerio the noo and wave goodbye to Scotland. It’s time to venture south on your return journey through England to London, but not before you come face-to-face with Hadrian’s first-century attempt to keep the ‘barbarians’ out of his Roman Empire. You’ll not see an ancient Roman wall like it anywhere else on earth. Continue to the walled city of York, where an orientation tour will guide you through its narrow medieval streets to the 13th-century Gothic cathedral, York Minster, which dominates the city. You’ll have some time to admire the structure’s beautiful stained glass before an evening on your own, although York’s alluring history may keep you on the edge of your seat. Delve into its tales of Romans, roses and ghosts. It’s the stuff great books are made of.
