Princess Diana is buried on the grounds of her childhood home at Althorp in North Hampshire, England.

But conspiracy theorists are convinced that this isn’t really where the Princess of Wales’ remains could be found. Rather, there are rumors suggesting that the late royal’s body is buried in the Spencer family vault at St. Mary’s Church.

According to Mirror UK, what has been fueling the conspiracy theory is the fact that there is still a visible trail of cement that reportedly shows where the vault was opened around the time of the Princess of Wales’ death.

Royal fans have also been encouraged to stay away from the crypt since there are heavy security measures being employed in the area. Motion sensors have also been installed to catch anyone trying to get beyond the gates.

The Spencer family vault houses some of the bodies of the late Princess Diana’s relatives including her father, John Spencer, who passed away in 1992 following a heart attack.

Royal fans thought that this is also where they could find Prince Charles’ ex-wife’s body after they learned that there were instructions given to the church to dig a hole in the floor shortly after her death.

And there were also claims that Princess Diana’s only brother, Charles, Earl Spencer also planned on burying the late royal there but they eventually decided to bury Princess Diana in Althorp.

Charles, Earl Spencer considered Althorp so that Prince William and Prince Harry could have instant access to their mom’s grave. However, royal fans are still not convinced that Princess Diana is really in Althorp.

Some of them believe that this was only the information that was shared with the public to ensure that no one else would have access to Princess Diana’s body in her family’s vault.

But as of late, Prince William and Prince Harry have not been photographed at the vault, which means that their mom can’t possibly be buried there.
