One of the best known Orcadian tombs is
Unstan in Stenness .
The chamber of five compartments is of average length,
but is covered by a round cairn. The passage enters the long side of the
chamber thus allowing two end compartments both of which have had shelves,
and a kerb across their entries. Another feature to note is a cell accessible
from the opposite side of the chamber to the passage. The cell is entered
between a pair of low portal stones, it has a back-slab but dry-built walls,
and is roofed by a capstone at a height of only 1.26 m.
When the tomb was excavated last century the finds included
fragments of distinctive shallow bowls with decorated collars . Such shallow
bowls are now known as Unstan Ware.
