Beng Mealea (Khmer: ប្រាសាទបឹងមាលា, its name means "lotus pond") is a temple in the Angkor Wat style located 40 km east of the main group of temples at Angkor, Cambodia, on the ancient royal highway to Preah Khan Kompong Svay.

It was built as hinduist temple, but there are some carvings depicting buddhist motifs. Its primary material is sandstone and it is largely unrestored, with trees and thick brush thriving amidst its towers and courtyards and many of its stones lying in great heaps. For years it was difficult to reach, but a road recently built to the temple complex of Koh Ker passes Beng Mealea and more visitors are coming to the site, as it is 77 km from Siem Reap by road.

Koh Ker (Khmer: ប្រាសាទកោះកេរ្ដិ៍) is an Angkorian site in northern Cambodia. 100 km northeast of Angkor itself, it was briefly the capital of the Khmer empire between 928 and 944 under king Jayavarman IV and his son Hasavarman II.After the Khmer empire had been established in the Angkor area (Roluos), Jayavarman IV moved the capital in 928 almost 100 km northeast to Koh Ker. Here a vast number of temples were built under his reign, until his successor returned to the Angkor area about twenty years later.

The Koh Ker site is dominated by Prasat Thom, a 30 meter tall temple mountain raising high above the plain and the surrounding forest. Great views await the visitor at the end of an adventurous climb. Garuda, carved into the stone blocks, still guard the very top, although they are partially covered now.

Preah Vihear Temple (Khmer: ប្រាសាទព្រះវិហារ) is a Hindu temple built during the reign of Khmer Empire, that is situated atop a 525-metre (1,722 ft) cliff in the Dângrêk Mountains, in the Preah Vihear province, Cambodia. In 1962, following a lengthy dispute between Thailand and Cambodia over ownership, the International Court of Justice (ICJ) in The Hague awarded the temple to Cambodia.

Affording a view for many kilometers across a plain, Prasat Preah Vihear has the most spectacular setting of all the temples built during the six-centuries-long Khmer Empire. As a key edifice of the empire's spiritual life, it was supported and modified by successive kings and so bears elements of several architectural styles.
