In Jukkasjärvi, a village a few miles east of Kiruna, the proprietors of one hotel begin planning for a winter ice festival in March. That’s when they begin collecting some 5,000 tons of ice from the River Torne in order to prepare the Icehotel, the world’s coolest place to stay. Options for overnight stay include snow rooms, ice rooms, art suites, and the Northern Lights room, all of which range from about $300 to $900 per night. But the deluxe suite’s the only way to go. These rooms come with a critical amenity: heated ensuite bathrooms and saunas. Here: A man walks into a room in the Ice hotel in Jukkasjarvi, Sweden, December 16, 2015.

Serge Huguenin of the Blondeau foundry takes the newly melted bell out of the mould in La Chaux-de-Fonds, Switzerland January 21, 2016. At this year's Summer Olympics in Rio de Janeiro, no matter how elaborate the opening ceremony or how sophisticated the live broadcasts, the final lap of athletics races will be announced the traditional way by ringing an old-fashioned bell. Omega, the official timekeeper of the event, has ordered 21 bells, forged almost entirely by hand by Blondeau's Bell Foundry in the Jura Mountains in Switzerland. Each last-lap bell is branded with the RIO 2016 logo and circled with the words “2016 GAMES OF THE XXXI OLYMPIAD”. (Photo by Denis Balibouse/Reuters)
