Ayutthaya: Thailand's Ancient Capital & Temple Ruins

Ayutthaya was the capital of the Kingdom of Siam from 1350 to 1767, when it was sacked and burned by the Burmese. At its peak, Ayutthaya was one of the largest cities in the world — a population of one million, with over 400 temples, and the commercial center of mainland Southeast Asia. The ruins left after the Burmese destruction are scattered across the island formed by the Chao Phraya, Pa Sak, and Lopburi rivers: broken chedis, headless Buddha statues, and the remnants of palaces whose original wooden structures have long since disappeared.

The site is a UNESCO World Heritage Site and an 80-minute train ride from Bangkok.

The Archaeological Sites

Wat Mahathat: The most photographed site in Ayutthaya — the temple where a Buddha head became entwined in the roots of a bodhi tree during the centuries of abandonment after 1767. The rest of the temple is extensive ruins: prang towers, chedi bases, and the remnants of the mondop. Entry ฿50.

Wat Phra Si Sanphet: The most important royal temple, within the palace grounds — three 15th-century chedis that held the ashes of Ayutthaya kings, still standing in their distinctive bell-shaped form. The symmetrical row of three chedis is the defining image of the city. Entry ฿50.

Wat Ratchaburana: Built in 1424 to enshrine the ashes of two princes who killed each other in an elephant duel over the throne — the internal crypt (accessible by a steep staircase) still has the original murals. One of the few temples where interior spaces are accessible. Entry ฿50.

Wat Chai Watthanaram: On the western bank of the Chao Phraya — a Khmer-influenced temple built in 1630 with a central prang surrounded by corner towers, reflecting the cosmological mandala plan. Best at sunset when the prang turns gold. Entry ฿50.

Wihan Phra Mongkhon Bophit: The hall housing one of the largest bronze seated Buddhas in Thailand — the image was cast in the 15th century and restored after the Burmese destruction. Free entry; the interior is active for merit-making.

Cycling the Ruins

The archaeological sites are spread across a 4 km² island — the most practical way to see them is by bicycle. Bicycle rental shops cluster around the train station and the Chao Phrom Market area, offering basic bikes for ฿60–80/day. The sites are connected by roads; the island circuit takes 3–4 hours at a relaxed pace.

Alternatively, renting a songthaew (฿300–400/half day) allows a driver to navigate between sites without the heat and effort — worthwhile if arriving in the hot season (March–May).

Getting There

By train: The most scenic option — departures from Hua Lamphong and Bang Sue Grand Station in Bangkok, 80 minutes, ฿15–35 (3rd class). Trains run approximately hourly. The station is on the east bank of the Pa Sak river; a ฿5 ferry crosses to the island.

By minibus: Faster (1 hour) from Victory Monument in Bangkok; ฿70 each way. Drop-off near the ruins.

By car/Grab: 75–90 minutes from Bangkok; private transfers available for ฿1,500–2,000.

Practical Notes

• Timing: 1-day trip is sufficient — most sites are within cycling distance. Staying overnight allows the ruins in early morning light, which is significantly more atmospheric
• Heat: March–May temperatures reach 38–42°C; the ruins have minimal shade. Avoid midday; start at 8 AM and take a break from 12–3 PM
• Wat Mahathat dress code: Shoulders and knees covered, even as a ruin — it is still a sacred site
• Combined with Bang Pa-In: The Royal Summer Palace of Bang Pa-In (20 km south of Ayutthaya) has 19th-century European, Chinese, and Thai buildings on an island — accessible en route from Bangkok
