According to Spain’s El Mondo newspaper, the unnamed man lost consciousness after being struck by lightning in the groin on Thursday night, with the bolt travelling down his leg and striking the ground.
His son called paramedics who later treated him for burns to the scrotum and feet at the scene in Madrid’s suburb Tres Cantos.
He was then taken to Madrid’s Hospital de la Paz where tests showed his heart and brain functions were not affected by the lightning strike.
The man is said to be in a stable condition in hospital.
The incredible story has unsurprisingly gone viral, with the original piece receiving over 1,000 tweets and 7,000 ‘likes’ on Facebook.
