From AP:
Much like the Olympic flame, there is another symbol of triumph and transcendence — far less known — that graces one host city after another: a one-of-a-kind, wooden Cross. The Cross of the Athletes has arrived in Milan for the Winter Games and holds pride of place beside the main altar in the Basilica of San Babila. It is one of the city’s oldest churches that — for a few weeks, while the cross is within its walls — holds the title of Church of Athletes.
The presence of the Cross at the Games is a tangible sign of the Catholic Church ’s belief that sport is a powerful way to bring people together. And this cross is unique in that it is made from pieces of wood sourced in five continents, an apparent nod to the five Olympic rings that convey the same sentiment.
