The Bat Tombs — formally the Archaeological Sites of Bat, Al-Khutm and Al-Ayn — are a UNESCO World Heritage Site about 25 km east of Ibri, containing one of the most complete collections of Bronze Age funerary monuments in the world. Hundreds of circular stone towers, ranging from one to three meters in height, are scattered across the rocky hillsides in an arrangement that still isn't fully explained. The most photographed are the Al-Ayn tombs, which line a ridge against a backdrop of stark Hajar Mountains.
The site is unfenced and unattended, which is either wonderful or alarming depending on your point of view — you simply drive up and walk among 5,000-year-old burial chambers. There is no entrance fee and no ticket office. The nearest settlement is the village of Al-Ayn, and the views from the tombs back across the Omani interior are striking. A visit pairs well with the Ibri Fort and souq to make a full day.
