Ovoo

Ovoo, oboo, or obo (овоо, , обоо, обаа, Traditional Mongol: , "heap"; Chinese: 敖包 áobāo, lit. "magnificent bundle [i.e. shrine]") are cairns used as border markers or shrines in Mongolian folk religious practice and in the religion of other Mongolic peoples. While some ovoos simply consist of a mound of stones, most have branches and khadag stuck into them. In the absence of stones, ovoos can be made entirely of branches, or even soil or sand. Ovoos are often found at the top of mountains and in high places, like mountain passes. In modern times, some of them have developed into large and elaborate structures, becoming more like temples than simple altars. They serve mainly as sites for the worship of Heaven and lesser gods led by shamans and kins' elders, but also for Buddhist ceremonies. Buddhist ritual surrounding ovoo has been dated back as far as the 16th century, but some scholars believe that the origin of ovoo dates back to prehistory. Texts used by Mongolian lamas to set up and perform offerings to ovoos were written by the third Mergen Gegeen in the 19th century. While the view that ovoos were remnants of Mongolian shamanism within Mongolian Buddhism was expounded by Buryat scholar Dorzhi Banzarov, ovoos have been found to only been used as markers instead of sacred sites prior to the rise of Tibetan Buddhism in Mongolia. Ovoo worship was officially prohibited along with other forms of religion during Mongolia's communist period, but a major revival since 1990 has seen it become one of the most prominent aspects of revived religious practice. Ovoos may have influenced or given birth to the Korean seonangdang. While Mongolia was under communist rule, ovoo worship was legally barred. In the modern era, mining operations pose a threat to ovoos. Ovoo are most often located on higher ground, like mountain passes and mountain tops. Ovoo can also sometimes be found near rivers or springs or at important crossroads. When travelling, it is the custom to stop and circle an ovoo three times, moving clockwise, in order to have a safer journey.
