Pong Lang Circle

Pong Lang Circle is a traffic roundabout in central Kalasin with a carved monument at its centre, built to honour the pong lang — the wooden xylophone that gives the province its musical identity. It’s free, unstaffed and viewable at any hour, since it sits in the middle of a public road junction rather than inside a park.

The monument marks a specific date: on 26 February 1989, Princess Maha Chakri Sirindhorn visited Kalasin’s College of Dramatic Arts and played two pong lang pieces herself. Kalasin has marked the date with an annual pong lang festival ever since. The instrument’s modern form is credited to Kalasin-born musician Pluang Chairatsami, later recognised as a National Artist for developing the ensemble style — pairing the wooden xylophone with khaen and drums — that spread the instrument well beyond the province.

The carving at the roundabout’s centre renders an oversized pong lang in stone, detailed enough to make out the string-bound wooden bars real instruments use. There’s no visitor centre or information panel cluster to work through — just the sculpture, visible from the road or from the pavement edge if you park nearby and walk over. Traffic circles this size in provincial Thai towns move fast, so treat it as a quick stop rather than a place to wander.

A real pong lang is worth hearing once you know what you’re looking at: 13 hardwood bars, hung on a slanted frame and struck with mallets like a marimba, producing a woodier, more percussive tone than the metal-keyed instruments used elsewhere in Thai classical music. Kalasin’s provincial identity leans on this instrument hard — school ensembles, festival stages and this roundabout all point back to the same February 1989 performance, and the annual competition it inspired still draws performers from across Isan every year.

Insider Tip: Combine it with the Mueang Kalasin Museum a short drive away, where you can actually hear a pong lang played rather than just see one carved in stone.

Watch out: This is an active intersection, not a pedestrian plaza — cross at the marked points and keep half an eye on traffic while you’re taking photos, especially around rush hour.

If Kalasin’s musical heritage interests you beyond a five-minute photo stop, Phrathat Yakhu — the province’s most important Dvaravati-era stupa — sits a short drive from the town centre and rewards a longer visit.
