Takeo Province, off Rte 2, 2 hours south of Phnom Penh

At the top of Phnom Chisor sit some very nicely preserved 10th/11th century AD Angkorian era ruins. The temple was constructed under King Suryavar-man I during a period when the Angkorian-era Khmer Empire was nearing its apex. As most Angkorian temples of the period, this temple is Hindu, dedicated to Shiva and Vishnu. Scenes including Brahma, Shiva and Vishnu are still visible, carved on some lintels and pediments. The 503 steps to the temple on top of the hill make for a fairly vigorous climb but the quality of the ruins and the amazing view of the countryside make the effort well worth it.
