The heartwarming clip, which was shared to TikTok by a woman called Michelle, known on the app as Schellywelly, begins with an elderly lady sitting on a sofa.

Text overlaying the footage reads: “Showing my 100 year old Armenian grandma the Etchmiadzin Cathedral in virtual reality.”

The camera then cuts to the grandma wearing a VR headset, as she is being told to look around her.

Overcome with emotion the woman begins saying “it’s so beautiful,” before appearing to let out a sob, then wipe her face with a tissue.

A man’s voice asks why she is crying and the 100-year-old responds again: “It’s so beautiful!”

The Etchmiadzin Cathedral is located in the Armenian city of Vagharshapat, which is where the grandmother grew up, and it is thought by some scholars to be the oldest Christian cathedral in the world.

Michelle captioned the adorable footage, which can be watched here, writing: “She is the most precious sweetheart [sad-face emoji] #fyp #cute #grandma #armenian #armenia.”
