This exhibition was possibly my favourite in Reykjavik, being an underground room in the centre of which are the remains of a Viking longhouse, dated to the year 871, plus or minus two years (hence the exhibition’s name). The house itself would be very interesting to see, being very well preserved, however the creators of the exhibit have not relied on this, instead creating a fascinating interactive exhibit on the surrounding walls, providing information on how Vikings lived and the history of the Icelandic people. There is also an interactive table with a plan of the house: you can click on different sections to find out about different areas, with text in Icelandic, English and even runic script. I found all of this incredibly interesting and spent about an hour there – not bad for what is effectively one room!
