アユタヤ王朝
Phitsanulok reached the peak of its historical import in 1463, when King Trailokanat moved the capital of the Ayutthaya kingdom to the city to strengthen the northern boundary of the kingdom. During Trailokanat's reign, Phitsanulok witnessed the construction of Wat Ratchaburana and Wat Nang Phaya. Around 1488, King Trailokanat's successor Boromma Racha III moved the capital of the Ayutthaya Kingdom from Phitsanulok back to Ayutthaya.
