The octogenarian was sitting on a bench in Alicante with his wife on Wednesday morning when the woman landed on top of him, having fallen from a seventh-floor balcony above, according to local newspaper Diario Información.
A spokesman for Alicante's city council confirmed to The Local that the incident occurred near the Plaza Manila, but could not give further details because the case is being handled by the national police.
The newspaper reported that the woman, 48, is believed to have been attempting to commit suicide and that neighbours said she suffered from depression.
The woman was taken to hospital, suffering from serious injuries, though she is in stable condition, according to El Mundo.
The man's wife was also taken to hospital, suffering from shock, according to Europa Press.
