Reyk­javík’s his­tory in a nut­shell. At Aðalstræti 10 and 16 in Reykjavík’s city centre, you can explore how the city developed from Iceland’s settlement period to the present day. Stretching underground from Aðalstræti 16 – which houses the archaeological remains of a 10th-century Viking longhouse – to the central Kvosin area’s oldest remaining building at Aðalstræti 10, this historical exhibition traces Reykjavík’s development from a farm to a city.
