There is one image of Ayutthaya that many people recognise immediately: an ancient Buddha head embraced by tree roots amid the brick ruins of the old city. We may have seen it on postcards, in travel books, photographs, or on our phone screens.
But if we pause to look a little longer, a more interesting question than “Is this image beautiful?” is this: Where in the city did this Buddha head once stand? Who created it? How did people pass by, bow, pray, or perform rituals before it? And how did a temple that was once part of everyday Ayutthaya become the ruin we stand looking at today?
The image of the Buddha head in the roots may not be the destination of the story, but its doorway. Looking through the roots, we find that behind this seemingly silent image once stood faith, power, people, craftspeople, rituals, and the life of a city existing together.
This is Wat Mahathat. Understanding this temple may allow us to see Ayutthaya in another way: as a city filled with people and networks connecting many worlds, and as a sacred space that helps us understand how the city gave meaning to religion, power, and place.
Wat Mahathat: More Than a Temple
If Ayutthaya was a city where geography, people, power, and networks from many worlds converged, Wat Mahathat is one of the places where we can see those relationships particularly clearly.
In the world of Ayutthaya, a temple was not simply somewhere people entered to perform religious activities before walking out again. Religious sites were part of the city, connected to faith, the monastic institution, the royal court, communities, rituals, and the organisation of urban space.
Wat Mahathat stands in an important area of the city island, near the capital’s central zone, and was one of Ayutthaya’s major religious sites. Thailand’s Inscription Database links the temple to the enshrinement of relics of the Buddha and states that construction began during the reign of King Borommarachathirat I, around 1374 CE, while it is thought to have been completed during the later reign of King Ramesuan.
Wat Mahathat’s importance therefore lies not simply in being a beautiful ancient monument, but in the question of what role it once played in the world of Ayutthaya’s people. The answer cannot be found in the prang alone. We must look at the entire site, at what remains, and at what has disappeared.
When a Place Becomes Sacred
Building a temple was not merely a matter of constructing buildings. Once a place was designated as sacred, its meaning changed. A space for travel became a space for ritual; a space for meeting became a place where people came into relationship with Buddhism.
Imagine Ayutthaya at a time when Wat Mahathat was fully functioning. People entered the grounds, monks carried out their religious duties, laypeople came to make merit, craftspeople worked with bricks, mortar, and other materials, and people took part in rituals. Some came out of faith, some as part of community activities, and others because of duties connected to the royal court or religious institutions.
We cannot know the lives of everyone from the evidence that remains, but we can read traces of these activities through buildings, spaces, objects, archaeology, and documents. This is why it is important to view a temple as a system of spaces, rather than simply as a single building.
When the Sacred Is Connected to Power
In Ayutthayan society, religion did not occupy one sphere while political power occupied another, entirely separate one. The royal court, religion, and the city were closely and complexly connected. The location of an important temple near the capital’s centre therefore links questions of place with questions of power.
Thailand’s Inscription Database identifies Wat Mahathat as one of the important temples and as the residence of the Supreme Patriarch of the Gamavasi monastic order. This reflects the temple’s significance within Ayutthaya’s religious structure.
However, calling the temple a centre does not mean that every activity in the city took place here. Nor does its connection with the royal court mean that the temple served only a political function. What we can see is that, in a city where Buddhism was a crucial part of the social order, placing an important religious site near the capital’s centre inevitably connected sacred space with the city’s structure.
Architecture That Speaks to Us
Try looking at the principal prang not simply as a tall structure standing in the middle of an archaeological site, but by asking why people in the past chose to create a sacred space in this form.
Architecture communicates through form, axes, levels, position, height, spatial organisation, and the relationship between buildings and the people who use them. The prang was therefore not merely something to view from outside, but part of the experience of the people who entered the space.
As we approach, the structure changes our sense of the space. When we look up, the height of the principal monument creates a visual hierarchy. As we move through different areas, the relationships between the buildings create a sequence of experiences.
UNESCO explains that Ayutthayan art developed through the adoption and adaptation of forms and influences from many sources, including those inherited from Sukhothai and Angkor, as well as influences from China, Japan, India, Persia, and Europe at different times. These influences eventually became a style distinctly Ayutthayan.
It is therefore too simple to say that Ayutthaya copied Khmer models or was shaped by a single outside influence. Culture does not travel like a blueprint. What arrives in a city is reinterpreted by the people who use it. The processes of receiving, adapting, negotiating, and creating new forms make architecture evidence of encounters between people and ideas.
The People Behind the Monument
When we look at the prang, we see bricks. People in the past saw labour, time, knowledge, and faith transformed into a structure.
Bricks had to be produced, materials transported, and builders equipped with knowledge of structures. Masons had to understand materials and forms, decorators needed skill, and labourers had to work together. All of this had to take place within a system capable of mobilising resources and labour.
We may not know the names of most of the craftspeople, and the names of many labourers barely appear in the chronicles. Yet the fact that a large building such as this could be constructed allows us to see the presence of those people through their work.
Ancient monuments are therefore evidence of people whose names often do not appear in history. History was not created only by the powerful, but also by the hands of countless others.
Buddhist Relics: Between Evidence and Memory
One important meaning of the name “Mahathat” is its connection with relics of the Buddha. Thailand’s Inscription Database states that Wat Mahathat was associated with the enshrinement of Buddhist relics, and that several inscriptions were found in the crypt of the temple’s prang. These help reveal the religious world and beliefs of people in early Ayutthaya.
Later archaeological excavations by the Fine Arts Department uncovered a stone reliquary and several stupas nested within one another. In the innermost layer, archaeologists found what was identified as Buddhist relics and accompanying objects. Some of these are now associated with displays at Chao Sam Phraya National Museum.
When discussing the temple’s construction and the enshrinement of relics, we should clearly distinguish between what archaeological and inscriptional evidence tells us and stories found in chronicles or accounts recorded later.
Existing evidence supports dating the temple’s construction to around 1374 CE, while the inscription database explains that it is thought to have been completed during the reign of King Ramesuan. Details about the transfer of the relics in 1384 CE appear in historical sources and presentations by some local agencies and public media.
We do not need to rush to turn these narratives into a single set of facts. More interesting is how people in the past told these stories about the place, and how those stories made the site sacred and meaningful. Memory is part of history, just as bricks, inscriptions, and artefacts are.
When a Monument Becomes a Ruin
Today we see Wat Mahathat through what remains: sections of wall, building foundations, the prang, chedis, broken sculptures, and countless bricks scattered across the site. But what we see did not come into being in a single day.
The transformation from a living temple into an archaeological site was a long process. The war and destruction of the city in 1767 was an important turning point, but the site did not stop changing immediately afterwards.
Information from Thailand’s Inscription Database states that Wat Mahathat was abandoned after the second fall of Ayutthaya. The principal prang also has a history of collapsing and being restored several times from the Ayutthayan period onward, before collapsing again during the Rattanakosin period.
Destruction, abandonment, deterioration, collapse, survey, and conservation should therefore be viewed as a continuing process. Some materials may have been reused, buildings deteriorated, and rain, sunlight, humidity, and environmental change continued to work upon the site.
What was once built to endure gradually became something later generations had to work to preserve. We must distinguish the history of the temple from the history of its ruins, and distinguish both from the history of conservation.
The Historic City of Ayutthaya was inscribed as a UNESCO World Heritage Site in 1991. This followed modern processes of defining the value of the ancient city, protecting it, studying it, and conserving it.
The Roots Embracing the Buddha Head
In photographs, we may feel that nature is embracing the Buddha image. But viewed through the eyes of history, the image is more complex than that. The roots are not simply a beautiful element in the composition; they show us how hundreds of years have worked upon this place.
Trees grew, roots entered the site, bricks and structures deteriorated, and the ground changed. What humans built and what nature created gradually became layered over one another.
However, we should not invent a story that the tree intentionally preserved the Buddha head, or create extraordinary events without evidence. Government tourism information identifies the sandstone Buddha head at Wat Mahathat as one of the site’s highlights and explains the roots covering the head within the context of changes following the fall of Ayutthaya.
What we know is enough. The image is the result of time, nature, and the overlapping history of the site. Nature and the ruins of the city are making time visible.
Reading the Ruins Again
After learning more about the temple, we might look at the image of the Buddha head in the roots once again. The first time, we may see a Buddha image. The next time, we may see a ruin. But if we look through history, we may see much more.
We see a temple that was once a sacred space; the people who used it; the craftspeople who built it; the relationship between religion and the city; the power structures that enabled a large religious site to exist; artistic forms created through the adoption and adaptation of outside influences; war and change that broke the city apart; nature transforming the ruins; and later generations returning to preserve and reinterpret what remained.
This is what it means to read an ancient monument. We are not reading only what remains, but trying to read what once existed through the traces of what is still here.
Wat Mahathat does not merely tell us how large a temple the people of Ayutthaya could build. It asks us how they thought about the sacred, the city, power, art, and memory.
When we ask these questions, the temple is no longer simply a building. It becomes a kind of document—not written in ink, but in brick, mortar, space, and time.
From Wat Mahathat to Thailand Through Time
Wat Mahathat shows us that within Ayutthaya there was a place that functioned as more than a structure. It was a space where religion, people, power, art, and memory converged.
If we look at the city on a map, we see roads, canals, walls, and the locations of buildings. But when we walk through the actual site, we begin to see meaning: who used the space, who created it, who had the power to define it, how people felt about it, and how its meaning changed over time.
This is why Wat Mahathat is important to the Thailand Through Time journey. We are not simply travelling to see an ancient monument. We are learning to read a city through the traces it has left behind—from the city to sacred space, and from sacred space we are about to enter the realm of power.
From Sacred Space to the Space of Power
If Wat Mahathat reveals the relationship between religion, the city, and its people, the next question follows naturally: as we approach the centre of the capital, how can we see the relationship between the city, the royal court, and power?
In Ayutthaya, space was not simply something we could see. The organisation of space was the organisation of relationships. If Wat Mahathat helps us read the sacred through the city, the next place will help us read power through the city: the Ancient Palace in the next chapter.
Wat Mahathat was not merely a temple associated with the enshrinement of Buddhist relics. It was an important space where Ayutthaya’s religion, city, people, power, and art converged.
An ancient monument therefore has value not only because of what remains, but because what remains still opens a path to understanding what has disappeared: the people, ideas, systems, faith, and world that once existed around it.
Try looking at Wat Mahathat again—not only through the image of the Buddha head in the roots, but through the people who built, used, and cared for this place; through the faith that created sacred space; through the power that organised the city; through the craftspeople who transformed ideas into architecture; and through the passage of time that changed a once-living temple into the ruin we stand looking at today.
An ancient monument contains not only what remains, but also a vanished world hidden behind it. Our task is to gradually read that world back into view.
