Probably you have heard about many horrifying places on this planet, but some places will cut your breath by their history. We all are terrified by cataclysms, earthquakes, tornado, and others. otherwise, several places could be scariest for your mental health like asylums, islands, prisons, and museums. It's time to dive into 10 of the most haunted places on this Earth.
1.Waverly Hills Sanatorium, Kentucky
In the early 1900s, this hospital was built in Louisville, Kentucky for patients that were a victim of the haunting disease of the time- tuberculosis. Many people died in this hospital; both from the disease and the inhumane tactics that were tested on patients to attempt to cure tuberculosis.
The death count got so high that the hospital installed a body-chute which is, as you can imagine, where the bodies of the dead victims were thrown. Waverly Hills shut down in 1961 and since then it has been the site of many ghosts TV Shows, as well as a haunted reputation by the community and the world. 
2.Helltown, Ohio
Welcome to the town of Boston, Ohio, otherwise known as the end of the world, and Helltown. This city has next to nothing going for it. In 1974 the state of Ohio made that city a national park because of its shockingly low population and history.
The small community of people living there etched insults into their walls to show the injustice of them being kicked out of their homes. The state later dropped the plans of the national park, leaving the abandoned, mysterious town of four tons of debate and legends. Legends such as a ghost boss, a satanic church, and a giant mutant python. The area around Boston, Ohio celebrates python day annually because of these legends.
3.Byberry Mental Asylum, Pennsylvania
This place was built in 1910 with the shambled scraps of what could be found after World War One shortage of materials. The Asylum didn't take long to fall apart both, economically and literally. The Asylum was handed over to the state of Pennsylvania but didn't end up in an acceptable state until 1953.
Through the exploitation of inhumane living conditions and treatment of patients, most staff left the asylum in the 1980s. They sent to demolish the building in 1991 but canceled a date upon finding millions of dollars in resources and materials inside. Leaving the building's abandoned until it was finally demolished in 2006 for a housing development.
4.Banghart Fort, India
Imagine a place so haunted that it became illegal to go to at night. Welcome to Banghart Fort in India. The history of this place is unsure amongst people. Everyone seems to believe one of two stories. One is a king going to live there and dooming the fort with the angle of the shadows completely engulfing the fort; the other story being a magician falling in love with a princess at the fort.
The magician attempting to trick the princess into loving him, the princess found that out and killed him. When the magician died, his final words cursed that Fort. Since then many people have recalled their unique and spine-chilling encounters at Bhangart Fort.
5.The White House, Washington D.C
Since the construction of the White House, there have been accounts from President, first lady, and senators of hearing or seeing strange entities.
The most notable case being the ghost of President Abraham Lincoln roaming the halls of the White House, Eleanor, and Franklin Roosevelt both reported seeing tall lanky figures in the Lincoln bedroom, which is now used as a study. Although no records show of anybody dying inside the White House and I would not be surprised if some presidents felt like they just didn't put enough overtime in the job.
6.Monte Cristo, Australia
A pregnant caretaker being thrown over a balcony, a baby being dropped down the stairs, and a poor boy being burned to ash in his sleep. All of these events took place in the notorious Australian estate named Monte Cristo.
This home was built in 1885 and has been constantly transferring owners due to the unfortunate and suspicious demise of the owners or the owners fleeing the home with fearful and sanity. The current owners bought the house in 1963 and since then one of the owners has passed away, but one was still alive. Olive Ryan claims that she has felt the presence, almost as commonplace to this point. One thing is clear about this estate; too much has happened for it to be coincidental.
7.The Amityville House
The most widespread haunted house in history. There have been tons of movies, books and legends made upon the basis of this house. Formerly a house to hold native Americans that were sick and insane. This home is notorious for the monstrous killings in 1974, where Ronald, the son, shot and killed his father, two brothers, and sister.
Ronald who is still alive today, then claimed that ghost had convinced him to commit the killings. Many years later a couple, George and Kathy Lutz, purchased the home. They claimed that paranormal anomalies had started to occur and they were increasing in intensity. The family immediately fled, probably for the better, and contacted paranormal geniuses Ed and Lorraine Warren to investigate. They reported that the house was definitely in the hands of evil entities and that none should ever dare enter the home for the safety of themselves.
8.Island of the Dolls, Mexico
Off the coast of Mexico, you will find the most bone-chilling island with an even more bone-chilling history. Don Barrera the caretaker of the island at the time, found a young girl washed up dead on the shore having near her a small dog. He hung the doll from a tree in memory of the girl, but from there the story says that the ghost of the girl took overdone and made him find and hang more dolls from the trees giving the island the creepy morbid look.
Then that little girl along with apparently other little girls that had died around the world found a haven on the island of the dolls. 50 years since finding the dead girl, Don Barrera was found dead himself in 2001 in the same place as the little girl died many years ago.
9.Stull Cemetery, USA
Named one of the seven gateways to Hell, Stull Cemetery in Kansas is said to be the courtroom of Satan himself. The legends revolve around a Church that was built there in 1867 and was used until it was randomly abandoned in 1908. Since then the walls started crumbling and the roof caved in.
The destroyed church was then said to be used by Satanists, which covens and Cults who would sacrifice animals. So, this Cemetery could become a gateway to Hell someday. I guess they got what they wanted and worshipped.
10.Poveglia, Italy
Welcome to Poveglia, a small island in the Venice Lagoon. This island has been a station of quarantine, a dumping ground for plague victims in a mental hospital. It's like every horrific setting from this list on one small island. The area is long since abandoned now and is overtaken by weeds, but because of all the death that is on this island is believed that 50% of the soil on this island is human ash.
This island doesn't mess around with teasing people that come over to visit the legend. There have been reports figures choking tourists to the ground, throwing them down to make their heads hit large rocks and even pushing them off the dock into the water. This island consists of an Old Bell Tower, a station for organizing a defense, a series of homes and a mental hospital for those that did not cooperate with the rest of society.
P.S. The unique methods to be saved in these places are the Holy Bible and Jesus Christ.
