Chiang Mai is one of those cities in Thailand where its ancient past is left crumbling alongside modern resorts being built. It’s a tangible history often left to its own fate, but still receiving daily reverence and offerings from local patrons. At one of these unsung temples in the southern outskirts of Chiang Mai, recent renovations uncovered a previously unknown history buried under its modern structures.

The Story of Wat Yang Kuang Temple

Passing by Wat Yang Kuang, you wouldn’t think too much of it. It lies in Haiya, a neighborhood in the southern part of the city outside which is off the radar of most tourists, who tend to stick to the Old City, the riverside, and Nimman neighborhoods.

Chiang Mai is home to hundreds of Buddhist temples. In fact, the city has the highest concentration of these wats of anyplace in Thailand. And, while many of them are massive tourist draws due to a unique design or their visible history (including dozens in ruins), most are passed by daily by tourists and locals alike. Wat Yang Kuang (sometimes written as Wat Yang Guang) is one of the less remarkable temples, despite its history going back nearly 700 years.

While there are no written records dating the temple’s origin, Wat Yang Guang is thought to be a location where King Mangrai rested while scouting the Chiang Mai Valley for a location to build his new capital, which would become Chiang Mai. During this time, Lanna continued on and refined its traditional Chiang Saen art style (also called Phra Singha style), which culminated in the Phra Saen Swae Buddha image. This massive cast bronze statue was housed at Wat Yang Kuang, where it would eventually be rediscovered, and is now housed in the Chiang Mai National Museum as its centerpiece exhibit.

Two centuries later, Chiang Mai and the Lanna Kingdom had fallen under the control of the Burmese Toungoo dynasty. During this period of Burmese occupation of Chiang Mai, Wat Yang Kuang was abandoned.

After a series of military campaigns led by King Kawila, Chiang Mai began an era of reconstruction under the Thonburi Kingdom’s (Bangkok’s) sphere of influence. During this period, new settlers from the Burmese city of Kengtung began rebuilding the Wat Yang Kuang, even naming it after Ban Na Yang Kuang, a town near Kengtung. This is why the temple features several Burmese design elements (maroon color, chinthe statues) today.

In 2006, Wat Yang Kuang began renovations to commemorate the 60th anniversary of the coronation of King Bhumibol Adulyadej (King Rama IX). These renovations led to the discovery of Wat Yang Kuang’s buried ruins in 2017. In that time, the surrounding ubosot was deconstructed and excavated by the Fine Arts Department. As of 2019, a new ubosot is being constructed over the excavated foundations of the centuries-old temple.


Visiting Wat Yang Kuang Temple

The first visit I made to Wat Yang Kuang was soon after reading an article on the discovery of 500-year-old ruins beneath the existing temple, albeit the article was over a year old at the time. During this visit, I didn’t bring a camera, but made it a point to stop in to see what, if any, ruins were actually dug up and now visible.

When I pulled into the parking lot, I was surprised to see the temple grounds literally torn apart and still under construction. Considering this important archaeological find occurred in 2017, 2 years prior, I expected to see some completion in terms of preservation of the finds, not a construction debris and building materials strewn about the entire temple grounds.

The dug-up ruins are those of an ubosot, the primary hall of worship in a Thai Buddhist temple. On my first visit, the excavated pit around these ruins was muddied by rains at the time. During subsequent visits, it was easier to gain get a closer view at the excavated temple ruins. Several layers of worn brick foundations are visible beneath ground level, although they are surrounded by a newly-built concrete foundation in order to build a new ubosot.

During this period, the ubosot’s main Buddha image was boarded off in a protective casing to spare it any damage from the construction.

At the base of this Buddha image is the most interesting part of the find. Here, colorful inlaid decorations and bas-reliefs adorn the bottom of the statue. At the time of each of my visits, these ornate ruins were not under the same protection as the Buddha image itself. They were instead very dirtied by the surrounding dirt and left to further damage from the elements.

How to Get to Wat Yang Kuang Temple

GPS Coordinates: 18.775800, 98.989021

The best place to start is Chiang Mai Gate (Pratu Chiang Mai) on the southeastern side of the Old City. From the gate, you will see the enduring ruins of Chiang Khong stupa wedged tightly between two modern shops.

Next to this is a street corner branching into Nantaram Road and Wualai Road. Turn left on to Nantaram Road and then stay on the left as it splits into Suriyawong Alley.

You’ll know you’re on the right road when you begin passing several other large ruined stupas on the east side of the road. After the largest of these (part of Wat That Klang), there will be a flat-topped brick gate on the west side of the road. This is the traditional entrance to Wat Yang Kuang. The entrance for cars and other vehicles is a couple meters further.

Hi all, my name is Ben. I’m a native Michigander with a passion for human culture and new places, and more than that, new experiences. I have degrees in archaeology and writing, pursuing a career in the latter. However, I never quite lost that fascination for archaeological theory. For the past 11 years, I’ve been living and travelling between Asia, Europe, and North America, documenting ancient sites and the peoples who built them, and then adapting them into practical archaeological travel information at

    Love the pictures and the story. Thanks for sharing!

  • Whoa! Your travels are amazing! My Grandmother was born in Beijing – in the Russian Quarter. Will you be traveling their? Or maybe you have already… I’ll have to see more of your blog. Blessings!

    • Ben says:

      Hi Annie, thanks for sharing. I actually haven’t spent any time in Beijing, or much of the east coast at all. The northern and central interior parts of China interested a bit more, although there’s certainly plenty around the Beijing I’d love to see as well. With winter coming up, I think I’ll avoid that for the next few months though.

      How about you–any plans for some time in China coming up?

    I love the way you introduce us to places… and I love Chiang Mai. Thank you!

  • I love “Ancient ruins discovered underneath xyz”. When Philadelphia was renovating the building that houses the Liberty Bell, they discovered slaves’ quarters underneath. Now they’re covered with glass so you can see. Fascinating!

What are your thoughts?
