Chester’s Eastgate Clock is said to be the second most photographed clock in England after Big Ben, which hardly seems fair given that Big Ben was never two years late for its own party. Built for Queen Victoria’s Diamond Jubilee in 1897, it wasn’t unveiled until 1899.

John Douglas designed it and his cousin, James Swindley, built it, setting the clock atop an 18th-century arch widened for stagecoaches on what was long the main road into the city. In its early years, someone climbed up and wound it by hand every week.

VoiceMap’s self-guided audio tours use the clock in two rather different ways. One, set in 1914, sends you sleuthing down wartime Eastgate Street, where a boy bugler would later sound the armistice. Another treats it as a lookout over the shop where Chester’s most famous ghost shrugged off an exorcism.
