Played around with this photo I shot in Reykjavík.

Dómkirkjan í Reykjavík
Dómkirkjan í Reykjavík

The Lutheran Cathedral was built 1788-1796 enlarged and renovated around 1847. At the time of its inauguration 1796, all inhabitants of Reykjavik found room in the building.
There has been a church on this site since around 1200 AD. The sand for the masonry was imported from Denmark as if there were no sand to be found in Iceland. It was in this church that Iceland’s national anthem was first sung in 1874.
