This prehistoric hillfort near Broomfield was reported by the Journal of the British Archaeological Association to have a tradition of vast buried treasure. There are supposed iron gates in the embankment that lead down to an iron castle deep underground. This castle is guarded by gnomes and goblins who make frightening groans to scare away anyone who might enter. To find the gates, one must dig in the night by the light of the full moon and they must dig in silence.
It is said that in the late 18th century a certain Dr. Farrar did indeed discover where the iron gates lay, by dowsing with a hazel rod on the day prior to the full moon. When night fell he returned, bringing a servant to do the actual digging; he told the man to dig within a circle he had drawn at the spot and to not stop digging until he hit the iron gates but to never utter a single word or sound, no matter what he may see or hear:
Meanwhile the Doctor stood by with his Bible. Then without warnign the spade struck metal. At once unearthly noises arose, and spirits swarmed out of the hole. Terrified out of all control the man yelled; "Lord have mercy on my soul!" At once the grisly guardians caught him by the leg and began to drag him down. But Farrar placed the Bible on the man's head with one hand and managed to haul him up with the other. Immediately after the sides of the pit caved in and the excavation healed over as if it had never happened.
