Near the village of Al Ayn, on the left side of the wadi are the best examples of beehive tombs dating back from the 3rd millennium BC.  It is a row of about 20 tombs on the crest of a small hill.  Just a few kilometres before Al Ayn is a turnoff to the left.  A signpost reads to Bat.  In the area around Bat the remnants of beehive tombs are found on almost every hilltop.  Close to the road near Bat are also the ruins of a large square house.

These two places give good evidence of Omani efficiency in using the architectural techniques in building the settlements and cemeteries in Bat.  The site was discovered in 1972 while actual excavations were carried out between 1973-1979.  Many cemeteries were distributed as groups located in Bat and Wadi Al Ayn.  Six round plain buildings were discovered, each building was surrounded with double walls and a well situated in the centre.  For it's historical importance, UNESCO included Bat in the World Heritage List.
