The infamous Amityville Horror house (left), located on Ocean Avenue in Long Island, New York; and Raynham Hall (right), in Norfolk, England are two of the most haunted places on Earth.
The house at Ocean Avenue in the Amityville area of Long Island was the setting of one of the most frightening demonic/ghostly infestations in history involving a family of five—the Lutz family—who stayed in the house, which they had just purchased, for a mere 28 days, before fleeing, taking nothing with them from the home except the clothes they were wearing at the time.
A nonfiction book by Jay Anson (September 1977) was a blockbuster best seller and has never been out of print; and the film, starring Margot Kidder and James Brolin, made in 1979, was also a big hit, and is still watched by new generations. There were a series of post-1979 sequels to the original film, and a scary remake in 2005 with Ryan Reynolds playing the part of Goerge Lutz).

The Brown Lady of Raynham Hall
Raynham Hall, a country house in located Norfolk, has been the seat of the Townshend family for 300 years. It is famous for being the location of a rare ghost sighting, that of the “Brown Lady”, who was captured descending the central staircase in one of the most famous ghost photographs of all time (above, left).
According to legend, the “Brown Lady of Raynham Hall” (left) is the ghost of Lady Dorothy Walpole (right) (1686–1726), the sister of Robert Walpole who was the first Prime Minister of Britain. Dorothy was the second wife of Charles Townshend, who was notorious for his violent temper. The story goes that when Townshend discovered that his wife had committed adultery with Lord Wharton, he punished her by locking her in her rooms at Raynham Hall. (There is another story, according to Mary Wortley Montagu, which states that Lady Dorothy was, in fact, entrapped by the Countess of Wharton at Wharton’s house—where she had invited Dorothy to stay for a few days. knowing that her husband, Lord Wharton, with whom Dorothy had been intimately involved, would never want Dorothy to leave, not even to see her own children.) Lady Dorothy Walpole is said to have remained at Raynham Hall until her death in 1726 from smallpox.
