Significant portions of the existing building are original parts that have been preserved for over 800 years.
That church had been torn down around the same time as this building and they were both similar in age and design.
The church was constructed in Lom Municipality from materials deliberately drawn widely from around Norway, including timber from Røros, shingles from Odalen, tar from Skjåk, wrought iron from Vågå, and a doorstep from Holtålen.
The project was supported by a Norwegian government grant of 5.5m Norwegian kroner; Icelandic government funding for the redevelopment of the Skansinn area of Vestmannaeyjarbær as a heritage area; and some private sponsorship was also involved, most importantly that the Icelandic company Eimskip shipped the church to Iceland for free.
