The pilot whales had been slaughtered for their meat and blubber, while an unborn calf had also been cut from the womb of its dead mother.
People, including young children, could be seen looking on at the bloody animals on the dockside, with many stopping to snap the dead mammals lying just metres away.
The killings are a centuries-old tradition on the Faroe Islands, known locally as a 'grind' or 'grindadrap'. It apparently helps feed the population of the remote Atlantic community over winter.
But while the Faroese claim the practice is both sustainable and regulated by law, campaign groups say it is inhumane and are calling for such hunts for banned.
Charity Sea Shepherd UK documented the killing on Friday 2 August in the bay of Hvalvik, saying this is the 10th whale hunt on the Faroe Islands this year - with 536 pilot whales slaughtered in total.
In September 2018, the charity offered the Faroe Islands €1m (£920,000; $1.1m) for 10 consecutive years with no whale hunts.
A spokesman for the campaign group said: "Over the course of the lengthy drive more and more members of the public and tourists could be seen stopping along the coastline to watch the family of pilot whales struggle and resist.
"As is often the case, the grind was swiftly becoming a social event, with parents laughing and chatting as children played on the killing beach.
