The main sight on the small island is the Southcairn, a 20 metre long chambered cairn dating from approx.

[8] The long, stalled cairn, built of local stone, was once a communal burial place for the bones of an ancient community.

Visitors can arrange privately for small boat access through the Co-op shop on Papa Westray.

“Eyebrow motif” carvings found in the southernmost chambered cairn bear a resemblance to the "eyes" of the Orkney Venus found at Links of Noltland on Westray.

"[9] William Thomson suggests that "perhaps Papay Tercia was the Holm of Papay — not a separate papar-site but a holm subsidiary to Papa Westray".
