This temple stands at the heart of the Old City, which is where travelers spend much of their time. Amidst the close sois, or alleys, and heavy motorbike traffic, Wat Prasingh rises at the end of Rachadamnoen Road. It is the largest wat in the city, and dates to 1345 when an ancient king built it in his father's honor. The father's ashes are still buried on the grounds - but don't let that spook you from visiting.
