Phra Nakhon Si Ayutthaya, Thailand

The city is located about 40 miles (64 km) north of Bangkok, at the confluence of the Chao Phraya, Lopburi and Pa Sak rivers, and on the main north–south railway linking Chiang Mai to Bangkok. The old city is on an island formed by a bend of the Chao Phraya on the west and south sides, the Pa Sak on the east side and the Klong Muang canal on the northern side.

Ayutthaya is geographically characterized as an island city surrounded by three major rivers: the Lopburi River to the north, the Pa Sak River to the east, and the Chao Phraya River to the south and west. The city's layout demonstrates sophisticated hydraulic engineering and urban planning, featuring an extensive network of man-made canals excavated for transportation, flood drainage, and domestic water supply. According to UNESCO, Ayutthaya was characterized by a systematic city-planning grid of roads, canals, and moats, supported by an extremely advanced hydraulic water-management system during the Ayutthaya period. During this period, the city was sometimes known as the "Venice of the East".

The internal canal system consisted of three primary north-south arteries that served as the backbone of the city's functional zones:

The Ayutthaya period is considered a formative era for Thai literature, characterized by the development of diverse poetic forms such as klong (Thai: โคลง), chan (Thai: ฉันท์), and lilit (Thai: ลิลิต). Early works were primarily religious or ceremonial, such as the Lilit Ongkan Chaeng Nam (Incantation of the Water of Allegiance).

The reign of King Narai (1656–1688) represented a major literary peak, during which the first Thai textbook, Chindamani (Thai: จินดามณี), was produced to formalize the language against increasing foreign influence. Other significant courtly works from this era include the epic poem Lilit Phra Lo and the development of nirat (travel poetry), which merged romantic themes with observations of journeys.

Beyond courtly literature, the period saw the emergence of popular oral traditions, most notably the epic of Khun Chang Khun Phaen. Although its modern written form was compiled later, the story originated as folk ballads (sepha) during the late Ayutthaya period, providing insights into contemporary social customs and daily life. The late Ayutthaya period under King Borommakot experienced a further resurgence of literature, focusing on Buddhist jataka tales and refined courtly poetry, and the Ramakien (the Thai version of the Ramayana), which became a foundational text for royal Khon (masked dance) performances.

Ayutthaya Wittayalai School and Chomsurang Upatham School are the principal secondary schools located in Ayutthaya city.

Phranakhon Si Ayutthaya Rajabhat University and Rajamangala University of Technology Suvarnabhumi are the two universities located in the city proper.
