Phanom Rung may not be the best publicised attraction in Thailand, but it can certainly push itself forward as one of the most impressive temple complexes in Thailand. Built between the 10th and 13th Century and fully restored in the 1980’s, it’s the largest and most authentic Khmer monument in Thailand and is one of the few not to have any later Thai additions.
Perched on the edge of an extinct volcano...
What a location, perched on top of an extinct volcano it presides from a position of power and offers superb views of the surrounding countryside into Cambodia, looking east towards the original Khmer Capital of Angkor. 
Travelling out here also opens you up to one of the least developed parts of Thailand, a region still largely dependent on agriculture, with a distinctive character and vigorous culture, where traditions are still celebrated during the many unique festivals.
Historically, as with most Khmer temples, it was originally built as a Hindu monastery. Your guide will take you through its history and as you climbed the steps worn down by centuries of pilgrims, you’ll admire the ancient carvings and sculptures that vividly show symbols and scenes from Hindu mythology. The whole complex has been beautifully restored allowing you to enter a world that disappeared so long ago.
Explore the history of the region
Phanom Rung is a perfect touring option for holidaymakers looking to get slightly off the beaten track and explore the history that peppers this region. A great add on is Prasat Muang Tam, a Khmer site just 15 minutes down the road. It’s situated at the foot of Phanom Rung and is built to the same plan as Angkor Wat, with 5 towers representing the 5 peaks of Mt Meru (home of the Hindu Gods) and the large baray (reservoir) opposite representing the ocean.
Both can be visited in a day and are ideal as part of a tour from Bangkok, perhaps also visiting Khao Yai National Park and Phimai, another impressive Khmer Temple complex. Travel further and you enter Cambodia and the chance to crown your holiday with a few days at Angkor.
Travelling east of Bangkok may not feel natural, but here you’ll not only enjoy Thailand’s rich historical heritage, but also discover a land less visited, not choked with back packers and coach tours, and more authentic for it.
