Update on the UNESCO World Heritage Site submission of Chiang Mai

Before you start reading this page I want to update you. From a source within the Chiang Mai World Heritage committee I heard that the Chiang Mai Provincial Authority Organisation (PAO) has decided to stop funding this project for the time being. We will keep you updated.

In 2020 and 2021 the Chiang Mai World Heritage committee has worked very hard on the submission of Chiang Mai to become a UNESCO World Heritage Site. The government decided though to submit the Si Thep Historical Park in Petchabun province to UNESCO this year. This means that Chiang Mai has to wait another year. Many people expected the Khaeng Krachan National Park to be the no.1 candidate of Thailand in 2020 but Si Thep Historical Park has won the submission. This Historical Park has been on the Tentative List of Unesco World Heritage Sites since April 2019.

At the 44th meeting, the UNESCO World Heritage Committee approved the listing of Kaeng Krachan National Park

World Heritage Sites in Thailand

For several years an effort is underway to get Chiang Mai inscribed on the list of UNESCO World Heritage Sites. There are six UNESCO World Heritage Sites in Thailand at the moment:

1) the Historic City of Ayutthaya

2) Historic Town of Sukhothai and Associated Historic Town

3) Thungyai-Huai Kha Khaeng Wildlife Sanctuaries

4) Ban Chiang Archaeological Site

5) Dong Phayayen-Khao Yai Forest Complex

6) Kaeng Krachan National Park

If all goes according to plan, Chiang Mai would become the seventh World Heritage Site in Thailand. The Dong Phayayen-Khao Yai Forest Complex was the last site to be inscribed on the list in 2005.

List of Tentative World Heritage Sites

Since 2015 Chiang Mai is on the list of Tentative World Heritage Sites of UNESCO. A team in Chiang Mai is working on the dossier that ultimately should succeed in convincing UNESCO to add Chiang Mai to the list of World Heritage Sites. There are six other sites in Thailand on the tentative list. Although it has nothing to do with the current UNESCO World Heritage effort, it is nice to look back at the first plan for historic and environmental preservation. This dates back to 1991.

Consultants of the Chiang Mai Planning Project, Louis Berger International Inc., and the Faculty of Engineering – Chiang Mai University prepared a document titled: Chiang Mai Policy-Based Action Plan for historic and environmental preservation. This final report is dedicated to Dr.Pairat Decharin, the former Governor of Chiang Mai. He was one of the primary sponsors of the Chiang Mai Planning Project. Dr.Decharin, his wife Supap and probably their only child Pasu died in the crash of the plane of Lauda Air on May 27, 1991.

Failure of the action plan

It appears that this action plan came to nothing after Dr.Decharin’s passing. The US Consul General Charles S.Ahlgren (1987-1989) wrote this when he was about to leave Chiang Mai: “Among the Thais, I have especially warm memories of the governor, Pairat Decharin, and his family. I was terribly saddened to hear of his death, and that of his lovely wife, in the 1991 Lauda plane crash. That accident not only took their lives and that of many of Chiang Mai’s leaders but dealt a blow to many development and planning activities in the town.”
The action plan mentions a number of things that still could be done such as continue and reinforce circulation patterns discouraging through traffic within the moat, restrict parking within the moat and establish and publicize a signed system of pedestrian walkways, just to name a few. The plan also mentions “Organise samlor tours of the area within the moat with fixed prices, starting points, and routes”. We already do this but it has to be organized and promoted much better. Please check out the Chiang Mai on Three Wheels website.
See below the action plan for historic and environmental preservation.

Chiang Mai and Lamphun: Twin Cities

The first time I heard about the UNESCO World Heritage undertaking was in 2013. In July Chiang Mai University’s Faculty of Fine Arts organized two seminars on the project to push for Chiang Mai and Lamphun to be one UNESCO World Heritage Site. One seminar took place at Chiang Mai University, the other at the National Museum in Lamphun.

I attended the meeting at the Hariphunchai National Museum in Lamphun. I remember there was much talk about the experiences of Luang Prabang with UNESCO. Afterward, every attendant received a black t-shirt with the slogan: Chiang Mai and Lamphun, a tale of two cities.

I think the idea was that Chiang Mai and Lamphun complemented each other. Chiang Mai is a global tourist destination and Lamphun is rich in history and culture. After this, I lost track of the World Heritage Project until early 2020. Some time along the way Lamphun was dropped as twin city: Chiang Mai is going for it alone.

Lanna Cities of North Thailand

In hindsight, it would maybe have been better if Chiang Mai would have cooperated with Lamphun and Lampang. These three cities have a lot of history and heritage in common. Sukhothai, Sri Satchanalai and Kamphaeng Phet form the World Heritage Site “Historic Town of Sukhothai and Associated Historic Towns”. Sri Satchanalai is about 130km from Kamphaeng Phet so the distance should not be an issue. Chiang Mai is closer to Lampang.

Chiang Mai, Lamphun, and Lampang have been part of the Lanna Kingdom for centuries and were ruled for more than a hundred years by the Chet Ton Dynasty. So it would have made sense to include both Lamphun and Lampang in the quest for a “Lanna Cities of North Thailand” UNESCO World Heritage Site, in my opinion.

Chiang Saen, the forgotten World Heritage Site

In the past couple of years I have visited the Ancient City of Chiang Saen several times. Chiang Saen should be inscribed on the UNESCO list of World Heritage sites, in my opinion. Unfortunately it is not even on the tentative list of World Heritage sites and there is also no initiative to get it listed. If you look at the sites that Thailand has submitted on this list, there is a strong case for Chiang Saen, I think. If the Si Thep Historical Park is listed, Chiang Saen certainly should be on there.

Chiang Mai on the tentative list

It was not until early 2020 that we heard again about the initiative to get Chiang Mai inscribed on the list of UNESCO World Heritage Sites. UNESCO added Chiang Mai to the list of Tentative World Heritage Sites on February 9, 2015. Chiang Mai is listed as “Monuments, Sites and Cultural Landscape of Chiang Mai, Capital of Lanna”. The “tentative” list is an inventory of properties that a country intends to nominate to UNESCO’s World Heritage List. A local committee is now working to draft the nomination documents.

The dossier of Chiang Mai UNESCO World Heritage Site focuses on historical sites in Doi Suthep-Doi Pui National Park, in the Old City, and in buffer areas around the park and the old city. The map below shows the main zone (property) in orange and the buffer zone in green. There are four groups of so-called attributes. You can find more information about the attributes here. In the core World Heritage zone are temples such as Wat Chedi Luang, Wat Phra Singh, Wat Chiang Man and, ofcourse, Wat Phra That Doi Suthep.

Submission to UNESCO

The various levels of the Chiang Mai municipal and provincial government must then endorse the draft dossier and forward it to the Ministry of Culture. This Ministry may wish to edit or amend the draft nomination dossier.  When they are satisfied with it, the Ministry will endorse the nomination to the Thailand National World Heritage Committee. The Deputy Prime Minister chairs this committee. It will then officially submit it through the Thailand National Commission for UNESCO to the World Heritage Centre. We will have to wait until 2022.

International Council on Monuments and Sites

Once officially submitted the UNESCO World Heritage Centre will perform a “completeness check” to ensure that all required parts of the nomination are included.  Once the nomination is certified as “complete,” they will forward the dossier to ICOMOS (International Council on Monuments and Sites). This is the officially designated “advisory body” responsible to evaluate all nominations made under cultural heritage criteria. There is another “advisory body” that is responsible to evaluate all nominations made under natural heritage criteria. This is the IUCN, the World Conservation Union. In the case of Chiang Mai, the IUCN will not be involved.

The evaluation process

The evaluation process is in two parts.  First, there is a desk review by a number of ICOMOS experts in the field.  While a minimum number of experts are invited to submit evaluations, in fact, at this stage in the process any member of ICOMOS may submit an expert evaluation of the nomination dossier.  This first stage desk review focuses on the criteria and attributes of potential outstanding universal value for which the property has been nominated.  It does not concern management issues.


If the desk review is positive, the nomination is then subject to a second stage evaluation which consists of an on-site inspection and evaluation of (primarily) management issues.  ICOMOS will appoint one or more experts to come to Thailand. They will work together with the Thailand National World Heritage Committee, the Ministry of Culture, local government officials, and the nomination drafting team. Together they will examine the management system in place to protect the nominated property’s potential outstanding universal value.  As part of this process, the evaluation team will hold public consultations with various stakeholder groups.

ICOMOS recommendation to the World Heritage Committee

ICOMOS then collates and synthesizes all of the evaluation data and draft a recommendation to the World Heritage Committee. There are four options of recommendation:
1) to reject the nomination on the grounds that the nominated property does not meet the criteria for inscription on the World Heritage list.
2)  to defer the nomination (meaning that the argument for inscription as World Heritage, while probable, is not convincingly presented and needs to be rewritten)
3) to refer to the nomination (meaning that there are pieces of information missing from the nomination dossier that need to be completed)
4) to inscribe the property on the World Heritage List.  The ICOMOS recommendation is shared and discussed with the National World Heritage Committee of the nominating State Party, who is invited to comment on the evaluation.

The World Heritage Committee

The World Heritage Committee debates in public plenary the merit of the nomination and makes one of four decisions: reject, defer, refer or inscribe.  The Committee may (and usually does) also adopt some mandatory recommendations for the improved conservation and management of the property. The State Party is required to report on, in writing, to the Committee over a specific course of time. This is usually annually for a period of 10 years, at which time the inscription is subject to review.
It is important to understand that the World Heritage Committee is not UNESCO.  UNESCO provides the secretariat for the Committee but does not make any decision on behalf of the Committee.  The World Heritage Committee is an independent 21-member committee.  The members are elected from among and by all the countries that have signed the World Heritage Convention. The World Heritage Committee is composed based on global geographical representation.  Members serve for a maximum of 6 years on a rotational basis, with 7 new members elected every 2 years.

Meeting of the World Heritage Committee

The World Heritage Committee meets once a year in July.  If the Chiang Mai nomination is officially submitted by 1 February 2021, the World Heritage Committee will consider the nomination at its meeting in July 2022. Due to the Corona crisis, there is serious doubt that the local committee will be able to finish the dossier in time to submit it in time. After finalizing the dossier it has to be approved by municipal, provincial and national bodies.

Update on the submission of Chiang Mai as a World Heritage Site

The Chiang Mai World Heritage committee submitted a nomination for voluntary submission to UNESCO in September 2020 after which the committee received the review and comments from UNESCO. 
The committee has submitted the nomination in January 2021 to the Ministry of Culture. It was then up to the government committee and, finally, a cabinet resolution to decide which site to submit to UNESCO in February 2021 as a possible World Heritage Site. The cabinet decided to submit the Si Thep Historical Park in Petchabun province.

Sites on the UNESCO tentative list

These sites are competing for the nomination. These have all been on the list of tentative sites of UNESCO. This list is an inventory of properties that a state party considers to be cultural and/or natural heritage of outstanding universal value, and therefore suitable for inscription on the World Heritage List.

The Commitment of Chiang Mai a la Carte

Chiang Mai a la Carte and our mother brand Green Trails are committed to contributing to the preservation of The Heritage of Chiang Mai and North Thailand. We actively promote the Living Heritage of Chiang Mai.
I fully support the submission of Chiang Mai to be inscribed on the list of UNESCO World Heritage sites. As Green Trails, we co-funded an NTCC meeting on the Chiang Mai bid to become a World Heritage Site on March 12, 2020, at the Old Chiang Mai Cultural Center.
Apparently, Khaeng Krachan National Park is the favorite in the race to become inscribed on the List of World Heritage sites. The park has been on the tentative list since 2004, which is much longer than Chiang Mai and other candidates in Thailand.
UNESCO was in 2019 on the verge of inscribing Khaeng Krachan on the list but stalled because of unresolved issues over the status of the Karen ethnic group living in the area.

Why Chiang Mai should become a World Heritage Site

Looking at the list of tentative sites I consider only the Khmer ruins in Buriram province and Khaeng Krachan National Park as serious competition. The impact of the status of a UNESCO World Heritage site for Chiang Mai would be much, much bigger than the impact to the other contenders.

The status would give the whole of North Thailand an enormous boost. It would strengthen conservation efforts in communities and stimulate responsible tourism. I have been to the Khmer ruins in Northeast Thailand and to Khaeng Krachan National Park and love those places. It would make much more sense to nominate Chiang Mai though.
