I was looking though my photographs from a visit to Iceland and came across a few that I'd taken inside the amazing Harpa concert hall in Reykjavic (https://en.wikipedia.org/wiki/Harpa_(concert_hall)).

It's an incredible structure of metal and glass; with multi-coloured and reflective geometric panels that hint at the lava columns in the surrounding landscape.

It's one of the most interesting and attractive buildings I've visited.
