The 2008 excavations at the Ness of Brodgar have been named runner-up in the prestigious Andante Travel Archaeology Awards.
The Orkney dig was beaten by a University of San Francisco project at the remains of the Roman city of Pompeii.
Previous recipients have been Volubilis, in Morocco, and Kerkenes Dag, in Turkey, as well as the Stonehenge Riverside Project.
In 2004, a team of archaeologists, led by Nick Card, of the Orkney Research Centre for Archaeology (ORCA), started uncovering evidence of a massive complex of structures that once stood between the two stone circles — an area of approximately 2.5 hectares that may have been used throughout the Neolithic period (approximately 3500-1800 BC).
Since 2004, the site has been the subject of annual excavations by ORCA and Orkney College.
