Korean Sacred Places: Temples, Shrines and Sacred Mountains

The idea beneath the places

Where Japan braids two faiths, Korea braids three. Buddhism, arriving in the fourth century, owns the mountains, the temples and the questions of enlightenment. Confucianism, the ruling philosophy of the Joseon dynasty, is less a religion of gods than a sacred order: the veneration of ancestors and the rites that bind family and state. Beneath both lies Korean shamanism, the oldest layer: the spirits of mountains, rivers and the dead, tended by mudang shamans. These are not rival congregations. Most Koreans have moved among all three without contradiction, and the sacred sites show it.

What looks today like serene retreat began, in part, as exile.

Almost every visitor asks why the temples are in the mountains. Buddhism was once the state religion of the Silla and Goryeo kingdoms, its temples in the cities. In 1392 the Joseon dynasty embraced Confucianism and turned on it. Over five centuries the new order stripped Buddhism's wealth, closed its temples and, in the end, effectively drove monks and nuns into the mountains. What looks today like serene retreat began, in part, as exile.

How to recognise it

A Buddhist temple (사, -sa)

Set in the mountains and reached by a wooded approach, it announces itself with a one-pillar gate (iljumun), then a gate of the Four Heavenly Kings. Look for vivid dancheong paintwork under the eaves, a main hall (daeungjeon) with a gilded Buddha, and stone pagodas in the yard. Names end in -sa: Bulguksa, Haeinsa. The common mistake is to treat it as a monument; most are working monasteries.

A Confucian shrine or academy

Restraint is the signal: unpainted wood, sobriety rather than spectacle, and no idols. Spirit tablets, not statues, are honoured. An academy (seowon) has a lecture hall and dormitories; an ancestral shrine (sadang) is smaller. They sit on a modest hill or by a stream near a village, with names ending in -seowon or -hyanggyo, or, at the summit of the order, Jongmyo. The mistake is to read the plainness as neglect.

A shaman or folk site

These are rarely signed; you come upon them. A small mountain-spirit shrine (sanshin-gak) behind a temple, carved jangseung guardian posts at a village edge, coloured cloths tied to trees, simple offerings on rocks, a sacred peak or spring. The mistake is to photograph an offering as decoration: it may be someone's prayer.

The mountain god at the back of the temple

Climb behind the main hall of almost any mountain temple and you will find a small, plainer shrine that belongs to no Buddha. This is the sanshin-gak, the shrine of the Sanshin or Mountain Spirit, usually painted as an old sage with a white beard and a tiger at his side. He is the far older shamanic god of the mountain the temple stands on. When Buddhism moved onto his slopes it did not evict him: it gave him a house at the back, alongside the Recluse and the Spirit of the Seven Stars. Korean Buddhism absorbed the old mountain faith rather than replacing it, and that is one of the most revealing things you can notice in Korea.

What changes across Korea

Confucianism has no gods and few images, yet for five centuries it was Korea's deepest sacred order. At its heart is reverence for ancestors, in the rites (jesa) still performed in many homes. At the summit stands the royal shrine of Jongmyo in Seoul, which keeps the spirit tablets of the Joseon kings. The Jongmyo Jerye, the ceremony performed there with ancient music and dance, is one of the oldest continuously observed royal rituals in the world, and is UNESCO-listed. Across the country, nine Neo-Confucian academies, the seowon, were inscribed by UNESCO in 2019. Where a temple overwhelms, a seowon composes.

Then comes Korea's biggest surprise. For all these temples and rites, around half of South Koreans today report no religion at all. Among those who do, Christianity is now the largest faith, roughly a third of the country, well ahead of Buddhism at around a sixth. Red neon crosses prick Seoul's night skyline. So these sites are not mainly the expression of a devout majority. They endure as living heritage, as places of practice for those who keep the faiths, and as somewhere even the irreligious go to pay attention.

Places that reveal it

Rather than rank Korea's sacred sites, it is more useful to see how differently the sacred is expressed. Each of these is covered in depth elsewhere on Great Wide Open.

Bulguksa and Seokguram

The masterpiece of Silla Buddhism, built when Buddhism was the faith of the state. A terraced temple below and a stone Buddha in a grotto above show what the religion made of itself before the long Joseon exile.

Woljeongsa and Odaesan

A forest monastery on Odaesan, reached along a kilometre of towering firs. It is the clearest picture of why the temples went uphill, and of how a place of exile became a place people walk to on purpose.

Sinheungsa and Seoraksan

A great temple at the foot of Korea's most dramatic mountain. Walk past its main hall and the mountain spirit's shrine is there behind it, the shamanic layer still tended inside a working Buddhist temple.

Haedong Yonggungsa

A rare coastal temple, built onto the rocks with the waves at its feet. Almost every other great Korean temple is in the mountains, which is exactly why this one, prayer at the edge of land and water, stands out.

Andong and the seowon

The Confucian heartland of clan villages and ancestral rites. Dosan Seowon, one of the UNESCO-listed academies, shows the sacred as moral order: unpainted halls, spirit tablets instead of statues, and study as a form of reverence.

A temple stay

The mountain temple entered not as a sight but as a discipline: dawn chanting, the 108 bows, temple food and tea with a monk. It is the one way a visitor is invited to take part rather than watch.

Beyond these, Haeinsa keeps the Tripitaka Koreana, some 80,000 woodblocks carved in the thirteenth century against the Mongol invasions, a day trip west of Daegu. In Seoul, Jongmyo is worth seeking out on any first trip.

How to experience it respectfully

At a Buddhist temple you are a guest in a working place of practice; at a Confucian shrine, a visitor to an ancestral rite; at a folk site, often an observer of someone's private prayer. You do not need to be an expert, and quiet observation never offends. A few principles carry across all three:

• Dress modestly and keep quiet. Cover shoulders and knees, silence your phone and lower your voice, because people are praying around you.
• Take your shoes off before entering any hall, and step over the raised threshold, never on it.
• Use a side door, not the central one, which is kept for monks. A small standing bow with palms together (hapjang) as you enter is welcome, never required.
• Do not point your feet at the Buddha when seated, and walk clockwise around pagodas and halls, following the direction of practice.
• Ask before photographing monks, worshippers or a ceremony, and heed no-photo signs inside halls. At a shrine or a folk site, the same quiet courtesy applies.
