Phnom Bakheng hill, perfect for sunset views, is a Hindu temple dedicated to Shiva. It was built at the end of the 9th century, during the reign of King Yasovarman. The temple-mountain has five tiers, with seven levels. At the base are 44 towers. Each of the five tiers had 12 towers. The summit of the temple has four towers at the cardinal points of the compass as well as a central sanctuary. All of these numbers are of symbolic significance. The seven levels, for example, represent the seven Hindu heavens, while the total number of towers, excluding the central sanctuary, is 108, a particularly auspicious number that correlates to the lunar calendar.
