Imagine a freezing city in the dead of winter. But instead of people tucked away inside and events and gatherings canceled until the snow melts, the city brings life to the coldest season of the year by throwing parties around fire pits, holding outdoor concerts under twinkle lights, and encouraging its residents and visitors to get outside on ice skates, bikes, and cross-country skis. These cities around the world celebrate the chillier months in a big way, proving that frigid weather doesn’t have to mean being shut in.
