It took 200 years and seven kings to build the Angkorian mountain temple of Preah Vihear around the year 1000. Perched atop the cliffs of the Dangkrek mountains, a region fiercely disputed over the centuries, it commands fabulous views over lowland Cambodia and brings to mind the past splendour of the powerful empire. These ruins, a marvel of both ancient architecture and nature, are a must-see for all, be they tourists seeing the sights or travellers looking for deeper meaning.
