To avoid any potential confusion with North Korea's capital, Pyongyang, the PyeongChang resort - which is just 50 miles south of the demilitarized zone that separates the two countries - changed its name for the Games, by capitalizing the "C."
The city lost by three votes to Vancouver for hosting duties in the 2010 Olympics, and by just four votes to Sochi for the 2014 event.
Development of high-speed rail lines was key to the country's Olympic bid, as Pyeongchang is rather isolated. The new train lines allow individuals to travel from Seoul to Pyeongchang in less than an hour.
In total, 13 venues, split between Pyeongchang and neighboring Gangneung, were used during the 17 days of the Games. Six new venues were built, and additional venues were renovated for the Games.
A record 102 medals were awarded in 15 disciplines.
