Though it's not yet near Indiana Jones levels, forest is slowly reclaiming this attractive ruin. The massive main stupa has collapsed, but several buildings still stand. It's northeast of the train station, well beyond the realm of most of Ayuthaya's visitors, so you'll likely have it to yourself. Wat Maheyong , a bit to the east, is larger, but less interesting, although the walled corridor leading to the ubosot (chapel) is an unusual feature.
