Ayutthaya Historical Park: the park, the town and the World Heritage site

The short answer

Three different things are called "Ayutthaya". There is the historic city, the Siamese capital that the Fine Arts Department says King U-Thong founded in 1350 and that lasted until an invasion in 1767. There is Ayutthaya Historical Park, the department's agency that maintains the ruins of that city.[6] And there is the modern town of Ayutthaya, which XTOUR treats as a destination in its own right.

UNESCO's World Heritage property, the "Historic City of Ayutthaya", is a fourth name for part of the same ground: a designation, not a separate place. ICOMOS, evaluating the nomination for UNESCO in 1991, noted that only part of the historic park was proposed for inscription.[1] None of the four is in Bangkok. XTOUR has no routing data and gives no travel time between them.

The city that was destroyed

ICOMOS's evaluation describes Ayutthaya as the second Siamese capital, from 1350.[1] The Fine Arts Department gives the same founding year, as B.E. 1893, and counts 34 kings before the city fell.[6]

The end was violent. The department dates it to an invasion in B.E. 2310, which is 1767, after which King Taksin moved the centre of the kingdom to Thonburi.[6] ICOMOS says simply that the city was destroyed by the Burmese.[1] Bangkok's own story begins afterwards: the Grand Palace's history page dates the move of the capital to the left bank of the Chao Phraya to 1782.[8]

The park

Ayutthaya Historical Park is the Fine Arts Department's name for the protected ruins and for the agency that looks after them. Its virtual-park site counts more than 300 historical sites on the island ringed by the Chao Phraya, Pa Sak and Lopburi rivers and in the area around it, among them a palace, religious buildings, an ancient bridge, a trade centre and traces of foreign communities.[6]

The sources give two different starting dates for the park. The department says its Ayutthaya Historical Park Project was established in 1982, after registering sites from 1935 and reconstructing Wihan Phra Mongkhon Bophit and Wat Phra Si Sanphet from 1956.[6] ICOMOS's 1991 evaluation says the site was classed a historic park in 1967.[1] XTOUR does not resolve the difference.

The department names the park and the Fine Arts Department as the main agencies that maintain the World Heritage areas and Ayutthaya's other historic sites.[6] For a visitor that means one public body is responsible for the ruins, and that body's pages are where opening hours, ticketing and site rules belong. XTOUR has not read those details on an official page, so it states none of them.

XTOUR does not show the park as one point on the map. It is an area of many separate sites, and a single point in its middle would put a visitor nowhere useful. XTOUR treats the individual ruined temples as the places, and the park as the name that ties them together.

The World Heritage property

UNESCO's 2002 list of inscribed properties records No. 576 as inscribed in 1991 on a single criterion, criterion (iii), under the title "Historic City of Ayutthaya and Associated Historic Towns"; the shorter "Historic City of Ayutthaya" is the name used by the World Heritage Committee's later decisions, the Fine Arts Department and ICOMOS.[1][6][4][3]

The property does not cover the whole historic city. ICOMOS said in 1991 that only part of the historic park was proposed for inscription.[1] In 2019 the World Heritage Committee asked Thailand to pursue an extension of the boundary to reflect the complete footprint of the City of Ayutthaya.[5] XTOUR has not read either boundary and does not assume the property and the park match, so it never treats them as one thing.

ICOMOS characterised the city by the prang, a reliquary tower, and by monasteries of gigantic proportions, naming Wat Mahathat and Wat Si Sanphet.[1] The explainer on what UNESCO inscribed at Ayutthaya and Sukhothai sets out the designation in more detail.

Ruins and working temples are different places

XTOUR does not assume that every wat in Ayutthaya is a ruin, or that everything standing on the old city's ground is part of the protected historic city. The World Heritage Committee's own decisions deal with modern building in and around the property: in 2015 it asked Thailand to refrain from new construction within the property and its setting, in particular within the footprint of the historic city, that may have an impact on the property's Outstanding Universal Value, and in 2019 it asked Thailand to implement the demolition order for a university Faculty of Fine Arts building.[5][4]

XTOUR treats the ruins of Wat Mahathat and Wat Ratchaburana as archaeological sites. ICOMOS names Wat Mahathat among the great monasteries and the crypts of Wat Raj Burana for their murals.[1] XTOUR has not read a source that says whether worship continues at either; if one shows that it does, XTOUR will describe it as a temple instead.

Names repeat. ICOMOS describes a Wat Mahathat at Ayutthaya and another at Sukhothai, two different monasteries in two different cities, and XTOUR keeps same-named temples apart.[2][1]

Sites XTOUR does not place in the town

The Fine Arts Department places Wat Chaiwatthanaram by the Chao Phraya River, outside the western island of Ayutthaya.[7] XTOUR has not read UNESCO's boundary map, so it does not say whether the temple is inside the World Heritage property, and it treats it as reached from Ayutthaya rather than inside the town.

The Arts of the Kingdom Museum is listed on the Grand Palace's website, and its page there places it at Koh Kerd, in Bang Pa-in district of Ayutthaya Province.[9] XTOUR does not place it in Ayutthaya town.

Planning Ayutthaya as its own destination

XTOUR plans Ayutthaya as a destination in its own right, with the ruined temples saved individually, rather than as part of a Bangkok stay. That is a statement about how XTOUR organises the trip, not about the journey: XTOUR has no routing provider, so it does not say how long the trip from Bangkok takes, how to make it or whether a return the same day suits you.

What XTOUR does not tell you

XTOUR does not publish opening hours, ticket prices, which ruins each ticket covers, entrance locations, accessibility or travel times for Ayutthaya. The Fine Arts Department manages the park and is the body whose current pages should be read for all of them.
