Taversöe Tuick (or Taversoe Tuick) is a Neolithic burial cairn on Rousay, Orkney, Scotland, thought to date from between 4000 and 2500 BCE. The monument includes a rare example of a double-tiered chamber, an upper chamber approached via a passageway and a lower subterranean chamber, originally separate, which can now be reached via a modern ladder from the upper chamber. It is unknown why the chambers were stacked in this way. The monument includes a third miniature chamber slightly downhill of the lower chamber, and linked to it by a small channel which has sometimes been called a 'drain' although that is not believed to be its true purpose.
