It’s not common in northern Europe, but there’s an element of personalisation of a grave when there’s a photo of the deceased on it. It gives that bit more information about the individual, perhaps their job, their likes or when they lived.
Magureanu was an actor who died in 2010, at the age of 56, having been born on 2 April 1954 in Giurgiu which is a Romanian city on the border with Bulgaria. The local paper published an obituary about Magureanu and his work, including mentioning that he worked at the National Opera House from 1979.
Without this photo that caught my eye, I’d have probably wandered past the grave, but it looked intriguing and interesting.
