Iceland: Skalholt Cathedral
Skalholt is the most importantly religious historic site in the country – 1056 to 1785 Skálholt was one of two episcopal seats in Iceland, and hence this was the most important political and cultural center. Until 1550, this was the heart of Catholicism, when the bishop and his two sons were beheaded and Iceland became Lutheran. Today’s cathedral is relatively new from the mid of 20th century, but inside it has a lot of relics from olden days. Interior is very austere and minimalist. Also next door is an old turf-roofed church, that is simply stunning.
