Chedi Ai & Chedi Yi

This location was once a princely battleground. Here, the two elder sons of King Intharacha (reign 1409-1424 CE), Ai Phraya and Yi Phraya, fought for the throne of Ayutthaya in 1424 CE. Both were severely wounded and died from the combat on an elephant. The youngest brother, Chao Sam Phraya, was then proclaimed King under the title of Boromaratcha II. He ordered two chedis built on the site where his brothers engaged in combat, and these can still be seen west of the bridge. The National Museum in Ayutthaya has been called after him.

In earlier days, this area, called Yan Pa Than, was a morning and evening fresh market selling various kinds of fruit such as oranges, bananas, sugarcane, and other fresh food. The market was formed with stalls, some permanent or mats on the ground, and was only functional in the morning and evening. There were about 40 of these markets within and without the city walls.
