For people who believe in the paranormal - ghosts, spirits, and other unexplainable encounters - most will agree that old hospitals and asylums are the most haunted places you can visit. With 13 chilling chapters, Haunted Hospitals delves into the history of the most infamous asylums, sanitariums, and hospitals on Earth, unlocking their dark histories and detailing their paranormal activities.

Take Waverly Hills Sanatorium, home to Mary, the apparition of a little girl who "wasn't normal". Left behind after a disease cut her young life short, Mary went from innocent in life to something more horrific in death.

Then there's Old Changi military hospital, where a history of wartime bloodbaths still stains the old abandoned halls - leaving behind chilling images in the minds of trespassers.

Or what about any of the other haunted hospitals contained within, where apparitions, disembodied voices, and strange occurrences are commonplace. With overcrowding and barbaric medical procedures being practiced, these buildings were the torture houses of the 20th century, and the eeriest haunts of the 21st.

Haunted Hospitals unlocks the dark histories of the most chilling abandoned hospitals from around the world. Every chapter describes the eerie and often frightening details of the best ghostly encounters. Are these sightings based on myth or true horrors? Only you can decide.
