Ayutthaya Historical Park

Thailand · 14.3516° N, 100.5575° E · 3 km² · 1 km from Ayutthaya

Ayutthaya Historical Park (Thai: อุทยานประวัติศาสตร์พระนครศรีอยุธยา (Pronunciation)) covers the ruins of the old city of Ayutthaya, Phra Nakhon Si Ayutthaya province, Thailand. The city of Ayutthaya was founded by King Ramathibodi I in 1351,[a] though it is likely to be significantly older, based on evidence showing that the area was already populated during the Mon Dvaravati period. Sources further mention that around 850 AD, the Khmers occupied the area and established a stronghold there, naming it Ayodhya, after one of the holiest Hindu cities in India of the same name. The early history of Ayutthaya is connected to this Khmer settlement. Additionally, Prince Damrong has also attested to the existence of a city named Ayodhya, founded by the Khmers ruling from Lopburi at the point where the three rivers meet. An excavation map shows traces of an ancient baray (water reservoir) close to the southwestern tip of Wat Yai Chai Mongkhon, which could have been built on a former important Khmer temple complex.

UNESCO's Description

Sukhothai was the capital of the first Kingdom of Siam in the 13th and 14th centuries. It has a number of fine monuments, illustrating the beginnings of Thai architecture. The great civilization which evolved in the Kingdom of Sukhothai absorbed numerous influences and ancient local traditions; the rapid assimilation of all these elements forged what is known as the 'Sukhothai style'.

More about Thungyai Naresuan Wildlife Sanctuary

UNESCO's Description

Stretching over more than 600,000 ha along the Myanmar border, the sanctuaries, which are relatively intact, contain examples of almost all the forest types of continental South-East Asia. They are home to a very diverse array of animals, including 77% of the large mammals (especially elephants and tigers), 50% of the large birds and 33% of the land vertebrates to be found in this region.

From the UNESCO World Heritage Centre (CC BY-SA IGO 3.0).

Climate and rainfall

The climate of the region is characterised by three seasons: a hot, wet season from May to October, a cooler, dry period from November to January and a hot, dry season from February to April. Average minimum and maximum daily temperatures range from 20 to 33 °C (68 to 91 °F) in the wet season, 15 and 35 °C (59 and 95 °F) in the hot, dry season, and 10 and 29 °C (50 and 84 °F) in the cooler season. Day-time temperatures can exceed 40 °C (104 °F) in April, while nighttime temperatures of 7 °C (45 °F) are not uncommon in the cool season.

The average annual rainfall decreases from the western part of the sanctuary receiving 2,000 to 2,400 millimetres (79 to 94 inches) a year to annual rainfalls of between 1,600 and 2,000 millimetres in the eastern parts of the sanctuary.

History

Paleolithic, Mesolithic and Neolithic stone tools have been found in the Khwae Noi and Khwae Yai River valleys and parts of the sanctuary were inhabited by Neolithic man. For at least 700 years, the Dawna-Tenasserim region has been home to Mon and Karen people, but burial grounds in Thung Yai and Huai Kha Khaeng Wildlife Sanctuary have not been systematically researched.

The Thai name "Thung Yai Naresuan" refers to the "big field" (thung yai) or savanna in the centre of the sanctuary, and to King Naresuan, a famous Siamese ruler who supposedly based his army in the area to wage war against Burma sometime during his reign of the Ayutthaya Kingdom from 1590 until his death in 1605.

Location and topography

The sanctuary is at the western national border of Thailand with Burma, in the southern area of the Dawna Range. It extends northeast of the Three Pagodas Pass from Sangkhla Buri District in Kanchanaburi Province into Umphang District in Tak Province.

The wildlife sanctuary stretches over an area of 2,279,500 rai ~ 3,647 km2 (1,408 sq mi), and is the largest protected area in Thailand.

Together with the adjoining Huai Kha Khaeng Wildlife Sanctuary (Thai: เขตรักษาพันธุ์สัตว์ป่าห้วยขาแข้ง) it constitutes the core area of the Western Forest Complex, which represents the largest agglomeration of contiguous protected area in mainland Southeast Asia, 6,222 km2 (2,402 sq mi).

Ban Chiang

Thailand · 17.5486° N, 103.3583° E · 62 km from Udon Thani

Ban Chiang (Thai: บ้านเชียง, pronounced [bâːn tɕʰīaŋ] ; Northeastern Thai: บ้านเซียง, pronounced [bâːn sîaŋ]) is an archaeological site in Nong Han district, Udon Thani province, Thailand. It has been a UNESCO World Heritage Site since 1992. Discovered in 1966, the site first drew attention for its red-painted pottery. Excavation has since recovered evidence of early agriculture, locally made bronze and more than a hundred burials, from which the health and diet of the people buried there have been studied.

The date of the earliest metalworking at the site is disputed, with proposals ranging from about 2000 BCE to about 1000 BCE. In 2008 the United States Department of Justice, following a five-year undercover investigation, raided several museums for their role in trafficking in Ban Chiang antiquities.

Si Thep historical park

Thailand · 15.4666° N, 101.1501° E · 9 km² · 93 km from Lop Buri

Si Thep Historical Park (Thai: อุทยานประวัติศาสตร์ศรีเทพ) is an archaeological site in Thailand's Phetchabun province. It covers the ancient city of Si Thep, inhabited from about the third to fifth century CE until the thirteenth. Its cultural periods run from late prehistory through the Dvaravati period to the golden age of the Khmer Empire. Si Thep was one of the largest known city-states of the central Thai plains in the first millennium. It was abandoned about the time the Thai-speaking cities of Sukhothai and later Ayutthaya rose as new centres of power in the Chao Phraya River basin.

The site gained the attention of modern archaeology in 1904 following surveys by Prince Damrong Rajanubhab, and it was listed as an ancient monument in 1935. The Fine Arts Department has undertaken continued study and excavations of the site, which has also been studied by archaeologists Prince Subhadradis Diskul, H. G. Quaritch Wales and Jean Boisselier, among others. Several ancient polities named in Chinese records, in inscriptions and in the Pali chronicles have been identified with the site, none of the identifications being settled.

More about Si Thep historical park

UNESCO's Description

This is a serial property of three component parts: a distinctive twin-town site, featuring an Inner and Outer Town surrounded by moats; the massive Khao Klang Nok ancient monument; and the Khao Thamorrat Cave ancient monument. Together these sites represent the architecture, artistic traditions and religious diversity of the Dvaravati Empire that thrived in Central Thailand from the 6th to the 10th centuries, demonstrating the influences from India. The local adaptation of these traditions resulted in a distinctive artistic tradition known as the Si Thep School of Art which later influenced other civilizations in Southeast Asia.

From the UNESCO World Heritage Centre (CC BY-SA IGO 3.0).

History

Si Thep was developed from a prehistoric farming village in the Pa Sak valley approximately 2,500–1,500 years ago. In the first archaeological phase (c. 4th–5th century CE), the early settlement of Si Thep occupied the inner town and there was a burial tradition with offerings related to India and communities to the central region and Moon River basin to the northeast.

Excavation has given the phase absolute dates. A burial group near the centre of the circular moated town, opened in 2016, held five human skeletons, a dog, pots, iron tools, a spindle whorl and two agate pendants. A tooth from a male of 25 to 35 returned a radiocarbon age of 1,730 ± 30 BP, or 240–390 CE. Thermoluminescence dates the circular moat to 414–602 and a ruin inside the rectangular extension east of it to 505–681.

Phu Phrabat, a testimony to the Sīma stone tradition of the Dvaravati period

Thailand · 17.7311° N, 102.3563° E · 6 km² · 37 km from Vientiane

The property illustrates the Sīma stone tradition of the Dvaravati period (7th-11th centuries CE). While sacred boundary markers for areas of Theravada Buddhist monastic practice vary in materials, extensive use of stones is found only in the Khorat Plateau region in Southeast Asia. Buddhism’s arrival in the 7th century led to an increase in the erection of Sīma stones throughout the region for over four centuries. The Phu Phrabat Mountain area preserves the largest corpus in the world of in situ Sīma stones from the Dvaravati period, testifying to the tradition that once prevailed in the region. The scale of Sīma stone erection and rock shelter modification has transformed the natural landscape into a religious centre, and rock paintings on surfaces of 47 rock shelters are the physical evidence of human occupation over two millennia.

Wat Phra Mahathat

Thailand · 8.4114° N, 99.9667° E · 1 km from Nakhon Si Thammarat

Wat Phra Mahathat Woramahawihan (Thai: วัดพระมหาธาตุวรมหาวิหาร) is the main Buddhist temple (wat) of Nakhon Si Thammarat Province in southern Thailand, a crucial trade crossroad between the Indian and Pacific Oceans. Founded in the 8th century, where a Hindu shrine once stood around 5th–8th centuries, the monastery has been a regional religious centre ever since. The main stupa of the temple, Phra Borommathat Chedi ('great noble relics stupa'), was built by King Sri Dhammasokaraja in the early-13th century to establish a symbol for the Theravada Buddhism sect in the region. The temple houses a relic of Gautama Buddha. The religious and local traditions have continued at the monastery for more than 1,500 years, including the Nakhon Si Thammarat chronicle tradition, the annual cloth-wrapping ceremony for the Great Reliquary and the Menora dance drama.

More about Wat Phra Mahathat

UNESCO's Description

Wat Phra Mahathat Woramahawihan (or Phra Mahathat monastery), located in Nakhon Si Thammarat Province in Peninsular Thailand on a narrow ridge between the Pacific and Indian oceans, has served as a major regional Buddhist centre since its founding in the 8th century. Benefiting from the transoceanic trade networks, the monastery was influenced by various religious and architectural traditions including Brahmanism, Hinduism, Mahayana Buddhism and Theravada Buddhism from northeastern India, central Java, Sri Lanka and the Mon region of southern Myanmar. These influences have been integrated into its religious buildings, rituals and cultural traditions. Its distinctive artistic and architectural expressions have exerted a wide-ranging and enduring influence throughout Thailand and across Southeast Asia. The religious and local traditions have continued at the monastery for more than 1,500 years, including the Nakhon Si Thammarat chronicle tradition, the annual cloth-wrapping ceremony for the Great Reliquary and the Nora dance drama.

History

According to the identical Thai and Sri Lankan legend, Prince Thanakuman and Princess Hem Chala brought the relic of Buddha to Hat Sai Kaew and built a small pagoda in 291 CE. The same tradition holds that King Si-Thamma Sokarat, on establishing the city of Nakhon Si Thammarat, built a new temple called Wat Phra Borom That on the same site, in the Mahayana manner of the ruling Srivijaya Kingdom. The city of Nakhon Si Thammarat was a prominent city in the ancient kingdom of Tambralinga. The city was a part of the Srivijaya empire till the early-13th century.
