I spent a couple of hours over at The Settlement Exhibition Reykjavík 871 +/- 2. I found it intriguing to see the remains of one of the first houses in Iceland. The house is over 1,000 years old. It really brings to life what the houses looked like at that time. There are plenty of video screens to learn about the migration of people, to the genetic makeup of the Icelanders, to the animals and trees that were native to Iceland and how the first settlers lived.
According to Wikipedia: “The Settlement Exhibition Reykjavík 871 +/- 2 is an exhibition on the settlement of Reykjavík, Iceland, created by the Reykjavik City Museum. The exhibition is based on the archaeological excavation of the ruin of one of the first houses in Iceland and findings from other excavations in the city center. The exhibition is located in 101 Reykjavík, on Aðalstræti 16, on the corner of Aðalstræti and Suðurgata. The focus of the exhibition is the remains of a hall from the Settlement Age which was excavated in 2001. The hall was inhabited from c. 930–1000. North of the hall are two pieces of turf, remnants of a wall which was clearly built before 871±2, hence the name of the exhibition. Such precise data dating is possible because a major volcanic eruption from the Torfajökull area spread tephra across the region and this can be dated via glacial ice in Greenland. The hall is among the oldest human-made structures so far found in Iceland. Also on display are objects from the Viking Age found in central Reykjavík and the island of Viðey.”
Also at the exhibit you can read parts of the Sagas and see some of the actual manuscripts! It is unreal how well some things hold up over 1,000 years. I think it’s a shame things made in this day and day barely last 10 years. Give yourself 2 – 3 hours there and then enjoy the city center as you will be right in the heart of Reykjavík city center.
