From information panel on site:
Today there are the remains of at least 60 Norse longhouses in the island, the largest number of rural sites anywhere in the Viking World. Three were excavated between 2006-2010 at Hamar, Underhoull and Belmont. Archaeologists discovered that none of the sites were exactly the same. Some had stone walls, some turf walls, some had beaten earth floors, some were paved with stones and one even had a wooden floor. This replica longhouse has been built using the information obtained during the excavations. It is based on the discoveries from Hamar, but has side rooms added - like those found at Underhoull.
