What was wonderful about our time in Iceland, was the weather was fabulous. It is almost never this nice! Reykjavik is a pretty modern city sitting on a lava plain. Founded by the Vikings, they maintain much of that heritage. Lonely Planet has a good web site for this city. The "Pearl" is the huge hot water tanks that originally supplied Reykjavik. It is now a giant museum and has a terrific observation deck where I took a panorama. The museum was undergoing renovation so we went up to the observation deck. The museum has its own website at this link.
A tour of Reykjavik's highlights
Huge Lutherin church built on the highest point in Reykjavik. Very controversial design, but dramatic for sure. Learn more at this site.
