Once the epicentre of Theravada Buddhism, the ancient region of what is now Sri Lanka had extended its border to Siam through the Buddhist faith. Its spiritual journey marked its beginning during the Dvaravati era (6th–11th centuries) and culminated with the adoption of Buddhism in Nakhon Si Thammarat, Sukhothai, Ayutthaya and Lanna.
A group of Siamese monks travelled to various religious historical sites in the Ceylon kingdom to follow Lord Buddha's footprints and their voyage was widely depicted in murals or on scripture cabinets.
