Hallgrimskirkja

This is the tallest church in Iceland, built of large hexagonal pillars made to look like a volcanic formation. Inside is an organ made of 5000 tubes - playing church of doom music inside as we entered, making me feel like I was in a horror movie!

I took the lift to the top of the tower and could see all of Reykjavik from the mountains on one side and the sea on the other.
