Kirkjubour is one of the earliest settlement in the Faroe Islands, dating back to around the 11th to 12th century. Right around Viking times.
I believe this stone building was one of the first dwellings, but there was no specific signage or notes in the info books.
The roof was recently rebuilt out of birch planks, covered with birch bark, which was in turn covered with sod. The two doors were about 40 inches tall.
