Borgarvirki (“the citadel”) is something that looks much better in person than it does in photos. I was impressed with its situation – it is very high up with far-reaching views. It is a natural basalt formation that was added to and used a fortress hundreds of years ago. It may just look like some rocks in these pictures, but when you are in it you do feel that you can see for miles and no one is going to get in at you.
I haven’t seen anything else like it in Iceland, and it’s worth a visit – but only if you have a 4×4 as the road is gravel, steep and with some potholes. See below for more photos.
