The aroma of burning wax wafts up the tree-lined slope of Svetozar Markovic Street in Belgrade's central Vracar district. Eventually, the source of the scent comes into view: votive candles, set against a wall of white flowers.
EDnews informs via BBC that the illuminated tributes stretch around much of the perimeter of Vladislav Ribnikar Primary School and the neighbouring high school.
On the barriers in front of the main entrance, there are pictures of the eight children who died in Wednesday's shooting, along with handwritten messages from friends and family.
Three girls sit on the pavement, silently holding each other. A little way down the road, a father talks quietly to his three daughters as they lay flowers. There are scores of people at the scene, with a steady flow of arrivals and departures, but there is no buzz - only a hush.
The contrast to my last visit to Vladislav Ribnikar could hardly be greater. In 2013, I filmed traditional slava celebrations at the school, a joyous occasion paying tribute to St Sava through song, dance and drama.
Now on the weekend of one of Serbia's biggest celebrations - the slava for St George - the country is in mourning. Not just for those who died on Wednesday, but the victims of another mass shooting near Mladenovac on Thursday.
There is also a sense of mourning for Serbia as people had understood it. In this country, schools had been safe and gun crime rare. Now, the two mass shootings have rocked Serbians' long-held beliefs about their society.
"Part of the shock is because no-one believed it could happen here," says graphic designer Ana Djordjevic. She has a 14-year-old son, and her niece is a pupil at Vladislav Ribnikar.
"My son told me he doesn't feel safe in school or on the street anymore, and that he cannot fall asleep. We need to give them time and space to process it and heal - and the teachers too."
For most Serbians, business as usual has been out of the question. "Belgrade never sleeps" is usually a proud boast about the city's proclivity for partying. This weekend, the mood is palpably subdued.
