King Narai Reign Fair 2027: Lopburi's Historical Festival

Lopburi has been holding its annual tribute to King Narai since 1988, and the fair has grown steadily into a ten-day event that turns Phra Narai Ratchaniwet — the king’s 17th-century palace — into the most theatrical space in central Thailand. Every February, the palace grounds host costumed processions, a period market, traditional Thai performances, and a nightly light-and-sound show that uses the palace walls as its backdrop. The 2026 edition was the 38th fair; the 2027 dates are to be confirmed by Lopburi Province closer to the time.

King Narai ruled from 1656 to 1688 and made Lopburi his second capital, away from the ceremony-heavy Ayutthaya court. He was the most outward-facing monarch of the Ayutthaya period: French ambassadors from Louis XIV visited, a Persian envoy held senior court positions, and European merchants traded through his ports. That diplomatic openness gives the fair its period character — alongside Thai costumes and court ceremonies, you’ll find French and Persian-influenced details in the historical re-enactment. Volunteers and officials dress in Ayutthaya-era garb for the duration, and the market sells period crafts, silverware, and food cooked to recipes the province promotes as historically grounded.

The historical procession is the event’s centrepiece. Hundreds of participants in period dress — soldiers, court officials, dancers, and elephant handlers — move through the town centre and into the palace grounds in a sequence that takes around an hour to pass. It usually runs on a weekend morning during the fair’s opening days. The procession route runs past several of Lopburi’s other Khmer and Ayutthaya-era ruins, which makes the staging more authentic than most reconstructions of this kind.

Pro Tip: The light-and-sound show is worth buying tickets in advance, particularly for the opening and closing weekends. The show uses the palace’s original 17th-century walls as projection surfaces, and the scale is better than the tourist crowds suggest. Weekday evenings mid-fair are the least crowded.

Lopburi’s other claim to attention is its macaques. The Macaca fascicularis population occupying Prang Sam Yod and the surrounding streets numbers in the hundreds and is entirely unintimidated by humans. They will take food from your hands, your bag, and your face. The town’s annual Monkey Buffet (a separate event, held in November) is the famous version, but the macaques are present year-round. Keep food in sealed bags, sunglasses off when walking near the shrine, and anything valuable in an inside pocket — the monkeys are genuinely quick.

The town is compact enough to cover on foot in half a day outside of festival activity. Prang Sam Yod (the “three-pranged” Khmer shrine, 12th-13th century), Wat Phra Si Rattana Mahathat, Kala Shrine, and the palace grounds sit within a 500-metre radius of each other in the old town. The combined site entry is around 150 THB for foreigners. The train station is 300 metres from the palace — luggage storage is available and the town rewards a same-day return from Bangkok rather than an overnight stay, unless the light-and-sound show is the specific draw.

February in Lopburi is dry and warm — daytime temperatures around 28-33 degrees Celsius, with cool evenings. The historical procession, palace grounds, and market together make a full morning or afternoon. Add the evening show and you have a satisfying day. Trains back to Bangkok run into the evening from the town station, and the journey time is consistently around 2.5 hours.
