Why the buildings differ
A traveller moving across Southeast Asia soon notices that temples look different from one country to the next. The differences are not random. They reflect local building traditions, the materials available, the influence of neighbouring courts, and the way each region absorbed Indian, Chinese and local ideas over many centuries. This article is a guide to recognising common forms. It is not a ranking, and it simplifies a great deal: real buildings blend styles, and many have been rebuilt several times.
Before comparing, it helps to know the basic ingredients. A stupa is a solid monument, usually containing relics. A temple hall or shrine house contains images and is used for worship. Many monasteries contain both, plus residences for the community. Reading sacred architecture begins by asking which of these a building is.
Thai wats
A Thai temple compound, or wat, is usually organised as a walled precinct containing several buildings. Among the most important is the ordination hall (ubosot or bot), which has boundary stones around it marking the consecrated area. Nearby is an assembly or image hall (viharn), and a stupa known as a chedi, often bell-shaped or with a slender spire. Roofs are typically steep and tiered, with decorated gable ends and curved ornaments at the eaves, often in glazed tiles of bright colours. The monks’ living quarters are usually at the edge. The Thai wat layout varies between regions, with northern examples often more modest in scale and wooden in detail.
In some Thai temples a tower called a prang, derived from Khmer forms, rises over the precinct. The prang at Wat Arun is a well-known example. The symbolism of the Wat Arun prang links it to Mount Meru, which brings us to a second point: many Thai towers are read as models of a sacred mountain.
Burmese stupas
In Myanmar, the stupa tends to dominate. The classic form is a bell-shaped dome set on terraces, tapering to a spire and capped with a metal umbrella called a hti. Many are gilded or whitewashed. The Shwedagon Pagoda in Yangon is the grandest example, rising from a wide platform surrounded by shrines. At Bagan, a different kind of building appears: brick temples with a hollow interior containing images, often topped by a stupa-like spire. The plain around them has been described as a landscape of stupas and temples, and is quite different from the single great monument of Yangon.
In Myanmar the word “pagoda” is generally used in English for stupas, which can confuse visitors who expect the multi-storey towers of East Asia. The shape is a stupa, not an East Asian pagoda.
Khmer prasats
Cambodia’s older monuments follow the Khmer tradition of the prasat, a tower with a stepped, pyramid-like roof built of stone or brick. Originally conceived as sanctuaries for Hindu deities or deified kings, many were later adapted for Buddhist worship. Angkor Wat is the most famous example, a temple complex with five towers arranged like the peaks of a mountain, and its history of changing from Hindu to Buddhist use is a good reminder that sacred sites may serve several faiths in turn. At the Bayon, large smiling faces carved on towers have given rise to numerous interpretations; the Bayon faces are commonly linked to a compassionate figure or to a king, though scholars disagree.
Today’s Cambodian Theravada temples, in contrast, often have colourful halls with pointed roofs and a separate stupa area. Khmer temple customs are closely tied to village life, and the temple grounds often serve the whole community.
Lao that
In Laos the key monument is the that, a stupa with a distinctive profile. A common form has a square base, a tapering body with lotus-petal motifs and a tall spire. The most celebrated example is Pha That Luang in Vientiane, regarded as a national symbol. Lao temple halls (sim) typically have low, sweeping roofs in layers, often with gilded stencilled decoration on dark wood or red walls. Luang Prabang has a refined local style, which scholars sometimes call by the city’s name.
Vietnamese pagodas
Vietnam looks different again. Its pagodas draw on Chinese Mahayana architecture, with courtyards, curved tile roofs, incense burners and halls for images of the Buddha and bodhisattvas. Multi-storey towers, in the East Asian pagoda manner, are found at some sites. Hanoi to Saigon temples differ between north and south, but the shared pattern is a series of halls leading to the main altar.
Indonesia’s single great monument
Borobudur in Java belongs to another world again: a stepped mountain-like monument of stone terraces carved with relief panels, crowned by perforated stupas, built in the 8th and 9th centuries. It is not a temple with an interior to enter, but a structure to walk around and up. Borobudur stupas and Buddhas can be seen from the upper terraces. The monument’s design is often interpreted as a map of the path to awakening, although specific readings vary.
How to use this guide
When you arrive at a site, ask yourself a few questions: Is there a solid bell or tower, or a hall with a roof? Does it taper in a stupa-like way? Are there tiers, terraces or hollow chambers? Where do local people place offerings and walk? The same questions apply whether you are in Thailand or Cambodia. Always remember that these are living places of worship. Dress modestly, remove shoes, move clockwise around stupas, and follow local guidance on photography and access.
