About Dobri Dobrev
Dobri Dimitrov Dobrev, better known as Grandpa Dobri, Elder Dobri or The Saint of Bailovo, was a Bulgarian ascetic who walked over 20 kilometres (12 mi) each day to sit or stand in front of the Cathedral of Alexander Nevsky in Sofia to collect money for charitable causes. Dobrev donated all the money he collected to charities, orphanages, churches, and monasteries. He turned 100 in July 2014. In Bulgarian, his name translates as "good" or "kind". Over the years, Dobrev became detached from the material aspects of life and devoted himself entirely to the spiritual world, specifically in the Orthodox faith.
