While most of France celebrates Bastille Day today, Emilie Petitjean will mourn the death of her 10-year old son, Romain, one of 86 victims in last year’s truck rampage through a holiday crowd on the French Riviera resort of Nice.

“The approach of July 14 is bringing back nightmares and anguished feelings that I thought I had overcome,” Ms Petitjean said.

“For those who have lost family members, there are scars that will never be healed.”

During last year’s Bastille Day celebration on the Promenade des Anglais along the Mediterranean Sea, a Tunisian-born French resident, Mohamed Lahouaiej-Bouhlel, 31, mowed down hundreds of people with a 19-ton truck shortly after the fireworks ended.

Besides those killed, 435 others were injured.

Today, the promenade shows no obvious scars. Older tourists in elegant straw hats sit on the iconic blue metal chairs that face the azure sea — the ultimate symbol of relaxation in Nice — as families and gaggles of teenagers linger while eating ice cream on their way from the beach.

The open-air cafes buzz with chatter and music. Still, things are different.

To commemorate the first anniversary of the attack, traditional Bastille Day festivities in Nice and neighbouring towns have been suspended or postponed this year.

Instead, a memorial ceremony will be held this afternoon in the majestic Place Massena, the main square lined with Italian-style neoclassical buildings, followed by a concert with the Nice Philharmonic Orchestra.

The seafront at the Quai des Etats-Unis will not be as lively – it will be a scene of remembrance all day today.

French President Emmanuel Macron and his two predecessors, François Hollande and Nicolas Sarkozy, will attend the sombre ceremony.

Afterwards they will meet with the victims’ families in private.

For Ms Petitjean, it won’t be the usual holiday of fireworks and food with her family.

It will instead be the culmination of months of planning for the anniversary ceremony, because she is president of the Promenade des Anglais victims association. The next step is creating a memorial for the victims.

Still, for those who lost family members or were seriously injured, no commemoration or memorial can heal the wounds left by that day, much less the shock of what happened.

Last year, Greg Krentzman and his family were visiting Nice from Culver City, California, and were at the Bastille Day celebrations.

A year later, Mr Krentzman, his wife and 10-year old daughter, Lola, are again here but aren’t sure they want to attend the ceremonies.

“My wife is a little bit nervous,” Mr Krentzman said about his French wife, Sophie. “There’s a big crowd and she’s hoping there will be security in place.”

While Sophie and Lola were able to avoid the truck, Mr Krentzman’s right leg was crushed by the impact, requiring a lengthy hospital stay in Nice. The attack left him with hefty medical bills and unable to work for several months.

“My daughter is young and doesn’t remember the incident so well, but my wife and I remember it pretty well. It has also hit my wife closely because she’s from Nice,” he said.

“It’s been a struggle. Some days are better than others,” he added.

“We are certainly better now because time does heal, but it’s still on our minds a lot. These things take a while to move from.”

That’s something Nice’s sizeable Muslim community also knows well: One-third of those killed by Lahouaiej-Bouhlel’s driving rage were Muslims.

Nice and the surrounding Alpes-Maritimes region are home to around 120,000 people who trace their origins to France’s former colonies of Algeria, Tunisia and Morocco.

“The people who do these things don’t have any humanity. They don’t want us to live together,” said Hanane Charrihi, 28. Her trauma was compounded by the hostile reaction she and her family faced in the immediate aftermath of the attack: Some residents heckled them on the streets as a “band of terrorists”.

“But the degree of support I have received has largely cancelled out the three or four negative comments I had,” she added.

Meanwhile, city leaders say Nice has shown its true face since the attack.

“The city has been resilient. It has rebuilt itself calmly and prudently, showing respect for everyone,” said Deputy Mayor Philippe Pradal. “The values of the republic are stronger than those who want to divide us.”
