If you choose to navigate the crawling vines and ivy shoots, the looming oak trees and the lichen-spotted tombstones of London’s Highgate Cemetery, then beware: this is considered by many to be the single most haunted place in the United Kingdom (Tower of London omitted, of course). The setting is certainly enough to curdle the blood, with age-old angelic figures hiding amidst the shadow growth, gargoyles laughing from the crevices, and endless rows of tombs running into the distance.
