The Incorruptibles
St. Bernadette was the original visionary at Lourdes, France and died in 1879 in Nevers, France. Her body was exhumed 30 years later in 1909 and was discovered completely incorrupt and free of odor. The body was again exhumed a second time ten years later in 1919 and was still incorrupt. Her body is still on display in the Chapel of St. Bernadette in Nevers, France to this day.
The causes for "incorruptibles" remaining free of decomposition have baffled scientists to this day. These bodies are discovered in many different environments, including environments that would typically cause an accidental or deliberately preserved corpse to decompose rapidly. They remain free of decay regardless of manner of burial, delay in burial, temperature, moisture, rough handling, frequent transference, having been covered in quicklime (a decaying agent), or proximity to other decaying corpses. They cannot be explained by science or reason. Some common characteristics of an incorrupt body.
Incorruptibles are typically found lifelike, moist, flexible, and contain a sweet scent that many say smells like roses or other flowers, as well flowing oils, perspiration, and flowing blood for years after death. They are  never embalmed or treated in any way due to the religious order's beliefs that the person came from.
These incorrupt bodies are on display all over the world to this day mainly in Europe.

Dashi-Dorzho Itigilov (1852-1927) was a Buddhist Lama of the Tibetan Buddhist tradition. During his lifetime he was selected to the post of the 12th Pandido Khambo Lama - head of Russian buddhists. He was a guest of the Russian czars and has helped Russian troops during WWI by collecting money and provisions. But the most interesting fact about him is the fact of his death legacy.
That was normally meditation ceremonies would take place at the time of one's death, he had requested that these take place while he was still alive. This was refused by the lama's, so instead he started the ceremonial rites himself. It was only after they realized what he intended that the lama's decided to join him with rites. In his last will and testament he asked that he be buried in the position his was body was in at the time, that was the lotus position. His remains were placed in a pine box at his request , his body was exhumed in 1955 and later in 1973 with the stipulation that only the monks were allowed to do this. Both times there was no signs of bodily decay. His clothes were changed and he was replaced back into his pine box.
His body was exhumed one more time in 2002 after communism had fallen in Russia, his body had been transferred to Ivolginsky datsan. Here his body was completely examined by pathologists, scientists and monks. Professor Viktor Zvyagin  Head of the Federal Center of Forensic Medicine declared that  the body was so well preserved to all tense and purposes it appeared that he had only died 36 hours ago..
