The chedi of Wat Yai Chai Monglhon is one of the landmarks of Ayutthaya, standing
high, and visible to all, who approach the city from the east, at par with Chedi Phukhao
Thong. The bell-shaped principal chedi stands on an elevated square base with smaller
chedis at the corners. There is a second octagonal pedestal above the base to
accommodate the bell-shaped body. Stairs lead up on the east side towards the first
terrace, and continue inwards the dome. Inside the dome we can see the chamber where
the relics were contained. Two mondops stand in the front, with their pyramidal upper
structures collapsed, exposing the Buddha statues inside.
