Because it was used as a base for the invading Burmese army, Wat Na Phra Meru is one of the few temples that escaped unharmed during the siege of 1787. A Burmese king died here when his cannon backfired during an attack, an event Thais feel adds to the spiritual power of the temple. Most visitors flock to it, however, because it is a rare intact example of 16th century architecture, and quite beautiful, its central sanctuary featuring stunning vaulted ceilings supported by ornate columns. The temple houses a 1.8m-tall (6-ft.) Buddha dressed in ‘royal attire’ (a common practice in the 18th century). It’s located on the Lopburi side of the river.
