The beautiful, glass-encased Harpa building was added to the Reykjavik skyline in 2011, a unique combination of Danish-Icelandic architectural design and visual artistry. Everything from its reflective exterior and element-inspired concert halls to its location on the old harbor (the meeting point of water and earth) is intended evoke a sense of the beauty and diversity of Iceland's natural surroundings, while also speaking to the country's evolving role as a major European cultural hub. Needless to say, this is heady stuff.
So what is there to do here, exactly? Well, Harpa puts on plenty of musical performances throughout the year, ranging (as they put it) "from classical to contemporary." If you don't feel like shelling out money for a ticket, you can at least stop inside and have a look around, as the building has a few restaurants, shops, and even a free concert series called "Undercurrent" meant to help expose Iceland's native underground artists. They also offer guided tours both weekdays and weekends for around $15 USD though, if you're feeling particularly daring, you could always just throw on a nice suit, stroll into a random conference hall and try to blend in (kidding). Either way, consider it worth a look, if only for a few minutes from the outside.
