Chorten is the phonetic form of Tibetan mchod-rten, a compound of mchod-pa (offering, worship, the acts by which one venerates a holy object or being) and rten (basis, support, that upon which something rests or which contains something of value). A chorten is therefore an 'offering-support' or 'worship-base' — a structure built to contain sacred objects and to serve as a focus for devotional practice. The word is the Tibetan translation of the Sanskrit stupa (from the root stup, to heap up), the Buddhist monument tradition that originated in India following the death of the historical Buddha Shakyamuni around 400 BCE. According to tradition, the Buddha's remains were distributed among eight kingdoms, each of which constructed a stupa over their portion. These original funerary mounds were the seed from which all subsequent Buddhist monument architecture developed, eventually generating the pagoda in East Asia, the chedi in Southeast Asia, and the chorten in the Himalayas.

The chorten's architectural symbolism is precise and explicit. Its basic form encodes a complete cosmological diagram: the square base represents the earth element; the hemispherical dome (the anda or 'egg') represents water; the conical spire represents fire; the crescent-moon finial represents air; and the solar orb at the very top represents the space element and the primordial mind of enlightenment. The thirteen rings of the spire represent the thirteen stages of spiritual development through which a bodhisattva passes toward full Buddhahood. The whole structure is therefore not merely a monument or a reliquary but a three-dimensional representation of the path of awakening and the nature of enlightened consciousness — a teaching in stone that requires no text to deliver its meaning. In the Tibetan tradition, eight canonical chorten forms are recognized, each commemorating a specific event in the life of the historical Buddha, from his birth to his death and parinirvana.

Chortens are found across the entire Himalayan Buddhist world: in Tibet, Nepal, Bhutan, Ladakh, Sikkim, Mongolia, and wherever Tibetan Buddhist culture has established itself. They are built at the entrances to villages and passes (where walking around them clockwise — keeping the chorten to one's right — constitutes an act of merit), at sites considered sacred by tradition, at places where an important teacher died or performed significant acts, and in monastery courtyards. The materials used range from unbaked mud brick in remote regions to elaborate gilt copper in wealthy monastic contexts. Some chortens are of enormous scale: the Boudhanath stupa in the Kathmandu Valley is among the largest Buddhist monuments in the world, while the chortens at Gyantse in Tibet and Rumtek in Sikkim are of comparable scope and complexity. Others are modest whitewashed structures of a few meters, indistinguishable to the uninformed eye from each other but significant to the communities that maintain them.

The word 'chorten' entered English through the accounts of Himalayan travelers, military expeditions, and colonial officials who encountered the structures throughout the late 19th and early 20th centuries. The British surveying expeditions that mapped the Himalayas and the early climbing expeditions to Everest and the other great peaks routinely noted chortens as navigational landmarks and cultural monuments. In contemporary English usage, 'chorten' is the term used specifically for Tibetan-tradition Buddhist monuments in Himalayan contexts, while 'stupa' is used for the Indian and Southeast Asian traditions. The distinction is practical rather than etymological: chorten is itself a translation of stupa, and the structures serve the same devotional function across all Buddhist traditions that maintain them.
