Ranworth Broad is reputedly haunted by a number of phantoms. These include the spectres of one Brother Pacificus and his dog, sighted aboard a spectral boat.
The other apparition that frequents the area is that of Colonel Thomas Sidney. Legend claims that in 1770, Sidney cheated in a horse race by shooting the steed of his challenger during the competition, which resulted in the death of the competitor. That night, the Master of the Wild Hunt claimed the soul of the Colonel as revenge.
