Seonangdang
The Seonangdang (Hangul: 서낭당), also known as the Seonghwangdang (Hangul: 성황당, Hanja: 城隍堂) are holy stone cairns or trees that are dedicated to the deity Seonangshin, the patron of villages. The Seonangdang still remain common in the mountainous settlements of the Korean Peninsula. History. The origins of the Seonangdang are unclear; archaeologists and historians have two theories. The first theory is that Seonangdangs originated in Korea. According to these historians, the Seonangdangs originated as border marks between various villages. As the concept of religion developed, these borders became worshipped as the homes of the border deities, equivalent to the  Roman deity of Terminus. These historians equate Seonangdangs with the Sodo, a holy area in the Proto–Three Kingdoms of Korea. Other historians claim that Seonangdangs developed as altars to Sanwang, the deities of mountains. The other theory is that Seonangdangs are the Korean variety of Ovoo, or Mongolian stone towers. The Mongolian worship of Ovoo are strikingly similar to the Korean worship of Seonangdang in that it is of stone, and is believed to grant the wishes of travelers. According to this theory, the Seonangdang cult followed the Mongol invasions of Korea, in the thirteenth century. However, there are  records of Seonangdang before that. The first record of a Seonangdang is in the "Goryeosa", a history book written about the Goryeo Dynasty in the 15th century. According to the book, in the reign of King Munjong of Goryeo, a 'Seonghwangsa', meaning 'Temple of Seonghwang', was constructed. In the Goryeo Dynasty, the best-known Seonangdang was in the town of Jeonju. King Gojong believed that the many defeats of the Mongols in the Mongol invasions of Korea were because the Seonangshin aided the Koreans. As one of the best-known deities to the Sangmin, or commoners, the following Joseon Dynasty  respected the Seonangshin. The Joseon government split the Seonangshin into two categories; the official Gukhaeng Seonang, the patrons of the state, and the private Seonang, the village patrons. The Joseon Dynasty rulers officially held rites in Seonangdangs. After usurping the Goryeo Dynasty with a coup, King Taejo of Joseon held ceremonies in the Seonangshin all throughout the peninsula. King Taejong of Joseon honored the Seonangdangs of Baekak and Songak (Gaeseong). Appearance and location. Seonangdangs were located on the hills or ridges near the village. There are five varieties of Seonangdang; Worship. The official government of Korea held jesa, or ceremonies , in Seonangdangs both regularly and at times of droughts and wars. In villages, both shamans and housewives prayed in Seonangdangs, but most of those who prayed at Seonangdangs were travelers and wanderers. On trails, travelers and wanderers placed three additional stones on the tower, and prayed for safety on the path, as it was believed that the deity would protect the travelers. Thus, Seonangdangs on popular trails could be extremely large and tall.
