Appearing like trenches dragged into the earth, sunken lanes,
also called hollow-ways or holloways, are centuries-old thoroughfares
worn down by the traffic of time. They’re one of the few examples of
human-made infrastructure still serving its original purpose, although
many who walk through holloways don’t realize they’re retracing
ancient steps.
