King Naresuan then marched his army to combat the invader. King Naresuan was full of rage
Pakaew asked him for the death penalty and suggested him to build a Chedi to celebrate the victory instead. King Naresuan the Great then decided to construct a large Chedi in this monastery named Phra Chedi Chaimongkhon. This monastery became "Wat Yai Chaimongkhon" later on.
