Ayutthaya Historical Park, Phra Nakhon Si Ayutthaya

The Ayutthaya Historical Park is a conservation area located in Phra Nakhon Si Ayutthaya District, Phra Nakhon Si Ayutthaya Province. It serves as the custodian of numerous ancient monuments within the region, which was once home to the majestic capital of the Ayutthaya Kingdom. The park encompasses the island city surrounded by three rivers—the Chao Phraya River, the Pa Sak River, and the Lopburi River—as well as surrounding areas. These areas feature royal palaces, religious sites, ancient bridges, historic trade districts, and traces of foreign communities. There are over 300 ancient sites scattered throughout the region.

Ayutthaya’s prominence began in the late 14th century, with historical records indicating that King Ramathibodi I (King U-Thong) founded the city in 1351 CE. Over time, the Ayutthaya Kingdom expanded its territories along river basins and southern coastal regions. It was ruled by 34 monarchs until its fall in 1767 CE due to invasions by neighboring kingdoms. Following this, King Taksin moved the capital to Thonburi, marking the end of Ayutthaya’s 417-year reign. During the Rattanakosin era, King Chulalongkorn designated the land within the island city as public property and initiated restoration efforts. The Fine Arts Department began surveying and registering significant historical sites in 1935, leading to systematic restoration projects starting in 1958 for landmarks like Wat Phra Si Sanphet and Wihan Phra Mongkhon Bophit. In 1981, the Ayutthaya Historical Park project was established to preserve these ancient sites systematically.

On December 13, 1991, UNESCO declared the “Historic City of Ayutthaya” a World Heritage Site, recognizing its global cultural significance.

Today, the Ayutthaya Historical Park spans 1,810 rai (approximately 724 acres), located within the island city of Ayutthaya, just 75 kilometers north of Bangkok via Asia Highway. The Fine Arts Department has registered an additional 3,000 rai of historical sites under its protection.

Historical Significance

Before King U-Thong established Ayutthaya in 1351, scholars believe that a settlement called Ayothaya or Ayothaya Sri Rama Thep Nakhon existed east of the island city. Evidence includes significant temples such as Wat Maha That and Wat Ayothaya. Chronicles also mention the creation of the Phra Chao Phanachet Buddha image at Wat Phanan Choeng, predating Ayutthaya’s founding by 26 years.

Ayutthaya’s strategic location, surrounded by three major rivers, provided fertile land, served as a transportation hub, and offered natural defenses against invaders. As a result, it became a dominant power over neighboring cities for centuries. By the 16th–18th centuries, Ayutthaya had grown into a major economic and trading center in Asia. Merchants from China, Japan, India, Persia, Arabia, Portugal, Spain, the Netherlands, England, and France sailed to Ayutthaya for commerce and diplomacy. Most foreign settlements were outside the city walls, except for Chinese, Hindu, and Muslim communities closely tied to the royal court, who were permitted to reside inside.

Ayutthaya also advanced in governance, law, society, religion, traditions, culture, architecture, sculpture, painting, fine arts, literature, music, and performing arts. These achievements laid the foundation for subsequent Thai dynasties, including Thonburi and Rattanakosin, many of which remain influential today.

Key Ancient Monuments

The island city of Ayutthaya, covering approximately 4,800 rai, is shaped irregularly due to river erosion. Its form has been likened to a gourd. Originally fortified with earthen walls and wooden stakes, brick walls were introduced during King Maha Chakkraphat’s reign (1548–1569). These walls were destroyed during Ayutthaya’s second fall and dismantled during the Rattanakosin period to prevent further use as a stronghold.

Ayutthaya was designed as a “water city,” with canals serving both transportation and flood drainage purposes. This network of rivers and canals was complemented by roads made of earth and bricks, with over 30 bridges—both wooden and brick—spanning waterways. Archaeological surveys have identified more than 425 ancient sites, though only 95 are within the 1,810-rai Ayutthaya Historical Park.

Notable Sites:

1. Ancient Palace (Grand Palace)

Originally constructed by King U-Thong in 1351, the Ancient Palace served as the royal residence and the political center of the Ayutthaya Kingdom. Over time, it evolved into a symbol of power and governance. After King Trailokkanat moved the royal palace to a new location along the Lopburi River in 1448, the original site was transformed into Wat Phra Si Sanphet, one of the most revered temples in Ayutthaya.

2. Wat Phra Si Sanphet

This iconic temple was once part of the royal palace complex and later became the spiritual heart of Ayutthaya. It was primarily used for royal ceremonies and housed three large chedis (stupas) that enshrined the ashes of Ayutthaya’s kings. Although the temple was heavily damaged during the Burmese invasion in 1767, its ruins remain a testament to the grandeur of the Ayutthaya era.

3. Wat Ratchaburana

Established in 1424 by King Borommaracha II, this temple holds deep historical significance. It was built on the cremation site of his two elder brothers, who tragically died in a power struggle over the throne. The temple is renowned for its well-preserved prang (tower) and crypt, which contains rare artifacts and golden treasures discovered during archaeological excavations in the 20th century.

4. Wat Mahathat

One of the most iconic temples in Ayutthaya, Wat Mahathat was built in the early 14th century during the reign of King Borommaracha I. It served as the religious center of the Ayutthaya Kingdom and housed sacred relics of the Buddha. The temple is famous for its grand prang (tower) and rows of chedis, though much of it lies in ruins today. Its most photographed feature is the head of a Buddha statue entwined by the roots of a banyan tree, symbolizing the harmony between nature and spirituality.

World Heritage Status and Cultural Legacy

The Ayutthaya Historical Park was inscribed as a UNESCO World Heritage Site in 1991 during a meeting in Carthage, Tunisia. It meets criteria highlighting its unique value as a rare testament to traditions and civilizations, some of which have vanished but continue to inspire. This remarkable heritage site attracts visitors from around the globe, offering profound insights into Thailand’s rich history and cultural evolution.
