If you’re in Reykjavík in December you spend most of your time trying to photograph the sky, which gets really interesting around sunrise and sunset. The picture above is from about 2:30pm local time, and you can see the orange glow of the setting sun in some of the buildings’ windows.
The church at the top of the hill is Hallgrímskirkja, which was under continual construction from the late 1930s through the 1980s.
