Chao Mae La-Ong Sam Lee Shrine
On a ledge below the main stupa of Wat Khao Phnom Phloeng is this squat mondop. The inner shrine is perched on a high platform, and was dedicated to a local goddess. The imges inside the building was originally of the goddess, rather than a Buddha image. Now, it is empty and you'll find nothing but a pit inside.
You have to look carefully, but behind the shrine is a path that leads down the spine of the ridge to a saddle, then up to Wat Khao Suwankhiri.
