Some of these buildings have survived to present times.
The Hofskirkja Church is one such building.
The roof is made of stone slabs and covered in turf.
It is one of six churches in Iceland still standing, which are preserved as historical monuments.
The church is maintained by the National Museum but also serves as a parish church.
In the 20th century this changed dramatically, as fewer and fewer turf-houses were being built.
