If you ever wonder what exactly happened to Dr. Jose Rizal’s remains, then you might have been shocked by a certain post by a renowned professor and historian about the Philippines’ national hero’s brain fragments.

According to Ateneo De Manila University professor Ambeth Ocampo, while the hero's mortal bones are famously interred beneath the Luneta monument, a piece of Rizal's backbone is kept in Fort Santiago.

"The chipped bone is believed to be the spot where the bullet hit him on December 30, 1896. I did not know till recently that Rizal’s eldest sister Saturnina kept fragments of the hero’s brain in a bottle," said in his caption.

"I presume the fragments were formerly preserved in alcohol that has since dried up," he added.

In the 1896 revolt against Spanish colonial power, Rizal's books "Noli me Tangere" and "El Filibusterismo" "were viewed as the guiding force for other patriots to rally for the country's cause," according to the National Historical Commission of the Philippines.

On the instructions of Spanish authorities, Rizal was murdered by firing squad on December 30, 1896, in Bagumbayan Field which is now called Rizal Park.
