Developing the Ayutthaya historical and archaeological body of knowledge 

       Phraya Boranrajathanin established Ayutthaya Study by means of integrating history with archaeology in a methodical manner. His noted publications on Ayutthaya include “Tamnan Krung Kao (Legend of the Old Capital)”, “Explaining Ayutthaya Map, an opinion by Phraya Boranrajathanin”, and “Bhumisathan Ayutthaya (Ayutthaya City Plan and Landscape)”. Phraya Boranrajathanin’s writings are the result of diverse stages of research on Ayutthaya history and surveys on the precinct of Ayutthaya ancient city, paving him the way for mapping important places and buildings of the old Ayutthaya. Until today, his three masterpiece writings have become principal sources for the study of Ayutthaya history and archaeological research.
