Interestingly, it was someone who mentioned the bonfire in Ålesund when it was commented that this fire of the Viking ship at Rubbestadneset had to be one of the finest in all of Norway.
Many thanks to​ @Singa for the very interesting comment about the celebration of midsummer in Norway.
You have done a thorough investigation and familiarized yourself with how Norwegians celebrated this event.
So your picture shows that people from Ålesund really make an impressively big and nice bonfire. The link below with Norwegian text has more information about the bonfire in Ålesund about how they build the bonfire.
