The biggest by far is the Pyeongchang Olympic Stadium which can host 35,000 people.
The smallest venue, the curling center in Gangneung, can still accommodate 3,000 onlookers.
The venues for the games are broadly split in to the bigger Pyeongchang Mountain Cluster and the Gangneung Costal Cluster. Pyeongchang and Gangneung are both located in the province of Gangwon in the North East of the country on the Sea of Japan.
