Dong Lakhon Ancient Town

Dong Lakhon Ancient Town is a Dvaravati-period walled settlement 9 kilometres from downtown Nakhon Nayok, its moat and earth ramparts still traceable on the ground more than a thousand years after the town was abandoned. There’s no reconstructed temple or visitor centre here — what survives is the shape of an old town cut into the land, plus the working Wat Dong Lakhon built inside its boundary.

The town’s oval core, known as Dong Lek, sits on a low plateau within a wider 6-square-kilometre hill area called Dong Yai. A moat and two concentric ramparts once enclosed it — the inner wall still stands 5-6 metres in places, the outer only 1-2 metres — running roughly 1.8 kilometres around. Four gates gave access, with the eastern gate at Nong Krapo serving as the main entrance. Historians read the layout as typical of Dvaravati-period towns: a fortified core for rulers, with the general population settled around it rather than inside the walls.

Two cultural layers show up in what’s been dug from the ground. The earlier phase, roughly the 9th to 11th centuries, belongs to Dvaravati culture. From the 12th to 14th centuries, Khmer and then pre-Ayutthaya influence took over — plausibly linked to Si Mahosot, another old town about 55 kilometres away in Prachinburi. Excavations carried out between 1972 and 2013 recovered broken terracotta, glass and stone beads, bronze bells and bracelets, gold leaf, and Buddha images carved in Baphuon and Bayon styles, tracking that shift from one culture to the next. By the 1300s the town was abandoned, its people apparently resettling along the rivers that now define modern Nakhon Nayok.

The name itself carries two competing local explanations. One holds that classical dance music (lakhon) was once heard drifting from the site on holy days, giving “Dong Lakhon” — the jungle of classical dance. The other traces it to “Dong Nakhon,” meaning simply the city in the forest. Either way, the Fine Arts Department registered the site as a National Ancient Site on 8 March 1985.

Insider Tip: Combine the visit with Wat Chedi Thong, which you pass on the way in from Highway 3076 — it breaks up an otherwise flat, shadeless walk around the earthworks with a shaded temple stop.

Watch out: There’s minimal signage translating the site’s history into English, and the ramparts are grassy, uneven ground rather than a paved trail — wear proper shoes and bring water, especially outside the cool season.

Dong Lakhon sits within easy reach of Nakhon Nayok’s dam and waterfall attractions — pair the archaeology stop with a half-day at Khuean Khun Dan Prakanchon, the province’s best-known reservoir, if you want to balance a history stop with something more scenic.
