Archeological items of interest on the island of Great Bernera (Bearnaraigh) are the standing stones at Cleitir beside the bridge, the remains of the broch on Loch Bharabhat and the remains of iron age houses at Bostadh. The last on was uncovered by erosion of the sand dunes exposing the site. A reconstructed house is nearby and is well worth looking at.
Despite the fact that there are inaminate rocks and stones of passing interest to some, the human stories are far more interesting. It was just off Bostadh at an island called Beirisadh that Niall the last chief of the Macleods of Lewis made his last stand against the Scottish Crown. Niall Macleod also had a part in the sinking of the pirate Peter Love's ship Priam in 1610. The remains of the ship and its treasure taken from an English merchantman is not precisely known but is thought to be between Circebost harbour and Bostadh.
