The city was ideally situated at the head of the Gulf of Siam, equi-distant between India and China and well upstream to be protected from Arab and European powers who were expanding their influence in the region even as Ayutthaya was itself consolidating and extending its own power to fill the vacuum left by the fall of Angkor. As a result, Ayutthaya became a center of economics and trade at the regional and global levels, and an important connecting point between the East and the West. The Royal Court of Ayutthaya exchanged ambassadors far and wide, including with the French Court at cosmopolitan culture and laying the foundation for the fusion of styles of art and architecture popular throughout the succeeding Rattanakosin Era and onwards.
Indeed, when the capital of the restored kingdom was moved downstream and a new city built at Bangkok, there was a conscious attempt to recreate the urban template and architectural form of Ayutthaya. Many of the surviving architects and builders from Ayutthaya were brought in to work on building the new capital. This pattern of urban replication is in keeping with the urban planning concept in which cities of the world consciously try to emulate the perfection of the mythical city of Ayodhaya. In Thai, the official name for the new capital at Bangkok retains “Ayutthaya” as part of its formal title.
