The ceremony’s organisers have said they sough to represent the city-mountain dichotomy of the particularly unusual setup for these Olympics while also trying to appeal to a sense of unity at a time of global tensions.
The Milan-Cortina Winter Olympics opened on Friday with a glittering ceremony at the San Siro stadium echoed by festivities at Games venues across the snow-capped Italian Alps.
The extravaganza reflected the most geographically widespread Olympics in history.
It culminated in the lighting of two cauldrons, one at Milan's Arch of Peace and one in Cortina d'Ampezzo, the chic resort 400 kilometres from Milan that is hosting the women's alpine skiing.
Alberto Tomba and Deborah Compagnoni, two Italian skiing Olympic champions of the past, lit an intricate cauldron inspired by Leonardo da Vinci's knot patterns at Milan's Arch of Peace.
In the freezing mountain air of Cortina, the task fell to Sofia Goggia, an Italian former gold medallist who had earlier taken part in a training run for the women's downhill event.
The ceremony in Milan showcased Italy's rich cultural heritage, with a nod to late fashion giant Giorgio Armani.
An otherwise harmonious event was punctuated by loud boos from the crowd when US Vice President JD Vance appeared on the big screen at the San Siro stadium.
But the US team received loud applause from spectators as they began their parade.
There has been anger in Italy over the presence of agents from the US immigration enforcement agency ICE as part of security for the American delegation, even though the Italian government has said the agents will not have any operational role on its soil.
The ceremony’s organisers have said they sought to convey themes of harmony and peace, seeking to represent the city-mountain dichotomy of the particularly unusual setup for these Olympics while also trying to appeal to a sense of unity at a time of global tensions.
South African actor Charlize Theron and Italian rapper Ghali delivered messages of peace toward the end of the night.
Performers at the San Siro show wore outsized heads of the three great masters of Italian opera, Giuseppe Verdi, Giacomo Puccini and Gioachino Rossini, while American pop star Mariah Carey, in a white sequined dress with feathers, sang "Volare" in Italian and "Nothing is Impossible".
Italian tenor Andrea Bocelli got a rapturous reception after performing "Nessun Dorma" and dozens of models honoured Armani by streaming across the stage wearing red, green, and white trouser suits.
Italian President Sergio Mattarella declared the Games open after International Olympic Committee chief Kirsty Coventry told the competitors: "You remind us that we can be brave, that we can be kind, that we can get back up, no matter how hard we fall."
In a first, 2,900 athletes paraded in the venues closest to where they will compete in the February 6-22 Games, in a bid to minimise travel.
The full collection of competition venues for the next two-plus weeks dot an area of more than 22,000 square kilometres.
The multi-city ceremony format allowed up-in-the-mountains sports such as Alpine skiing, bobsled, curling and snowboarding to be represented without requiring folks to make the several-hours-long trek to Milan.
