Discovered in September 2010, this tomb is quarried out of solid bedrock and is the only tomb of its kind. Evidence of Otter activity and Otter bones within the tomb gave rise to it being named 'Tomb of the Otters'.
Large quantities of Otter spraint and Otter bones were found inside the tomb, at many different levels, suggesting that it must have been left open - thus allowing Otters to come and go as they pleased.
A guided tour of the tomb is an experience unlike any other in Orkney today as it is the only partially excavated tomb open to the public which still contains human remains. from over 5000 years ago and gives the visitor an oppportunity to reflect on the lives of people who lives in Orkney during this Neolithic period.
