Haunted follies and drowned villages: Britain's eeriest Halloween trips

A Halloween travel guide rounds up spooky places to visit in Britain. Picks include the Racton Monument near Chichester, a folly commissioned by the second Earl of Halifax that is said to be haunted, and Wales's Pontsticill reservoir, built in 1927, whose bell-mouth spillway looks like a giant plughole and where a submerged village with a 15th-century church resurfaces during droughts.
