Since Grytviken sits on flat land in a well sheltered harbor (plus has a nearby fresh water supply with hydro capability), it became the primary whaling station in South Georgia with several hundred (seasonal) workers during the peak whaling years in the early 1900's. It was shut down in the mid-1960's as the whaling populated became depleted, but the rusting facilities still remain as a grim reminder of an unfortunate earlier era.
Grytviken is also well known as the final resting place of Ernest Shackleton ("The Boss") and his nephew Johnnie Shackleton led us in a toast at his grave. The incredible South Georgia museum is there also which not only chronicles the Shackleton saga, but general life and history of South Georgia.
