Integrity
The integrity of the property as the ruins of the former Siamese capital is found in the preservation of the ruined or reconstructed state of those physical elements which characterized this once great city. These consist of first and foremost the urban morphology, the originality of which is known from contemporary maps of the time prepared by several of the foreign emissaries assigned to the Royal Court. These maps reveal an elaborate, but systematic pattern of streets and canals throughout the entire island and dividing the urban space into strictly controlled zones each with its own characteristic use and therefore architecture. The urban planning template of the entire island remains visible and intact, along with the ruins of all the major temples and monuments identified in the ancient maps. Wherever the ruins of these structures had been built over after the city was abandoned, they are now uncovered.
In addition, the ruins of all the most important buildings have been consolidated, repaired and sometimes reconstructed.
