Sansa, Buddhist Mountain Monasteries in Korea. Sansa (mountain temple) is a term for any Korean Buddhist temple located on a mountain. Seven of these temples are designated as UNESCO World Cultural Heritage Sites since 2018. With the country being largely mountainous and Buddhism deeply rooted in its history, there are many sansas across the country. The word sansa is composed of two words, san and sa, which mean mountain and monastery/temple respectively.
