Things to do in Siem Reap

Angkor Wat(Opens in a new window)

Angkor Wat (Central Khmer: អង្គរវត្ត or "Capital Temple") is a temple complex in Cambodia and the largest religious monument in the world, on a site measuring 162.6 ha. It was originally constructed as a Hindu temple of god Vishnu for the Khmer Empire, gradually transforming into a Buddhist temple towards the end of the 12th century. It was built by the Khmer King Suryavarman II in the early 12th century in Yaśodharapura (Central Khmer: យសោធរបុរៈ, present-day Angkor), the capital of the Khmer Empire, as his state temple and eventual mausoleum. Breaking from the Shaiva tradition of previous kings, Angkor Wat was instead dedicated to Vishnu. As the best-preserved temple at the site, it is the only one to have remained a significant religious centre since its foundation. The temple is at the top of the high classical style of Khmer architecture. It has become a symbol of Cambodia, appearing on its national flag, and it is the country's prime attraction for visitors.

Bayon(Opens in a new window)

The Bayon (Central Khmer: ប្រាសាទបាយ័ន, Prasat Bayon) is a well-known and richly decorated Khmer temple at Angkor in Cambodia. Built in the late 12th or early 13th century as the official state temple of the Mahayana Buddhist King Jayavarman VII (Central Khmer: ព្រះបាទជ័យវរ្ម័នទី ៧), the Bayon stands at the centre of Jayavarman's capital, Angkor Thom (Central Khmer: អង្គរធំ). Following Jayavarman's death, it was modified and augmented by later Hindu and Theravada Buddhist kings in accordance with their own religious preferences.

Ta Prohm(Opens in a new window)

Ta Prohm (Central Khmer: ប្រាសាទតាព្រហ្ម, pronunciation: prasat taprohm) is the modern name of the temple at Angkor, Siem Reap Province, Cambodia, built in the Bayon style largely in the late 12th and early 13th centuries and originally called Rajavihara (in Khmer: រាជវិហារ). Located approximately one kilometre east of Angkor Thom and on the southern edge of the East Baray, it was founded by the Khmer King Jayavarman VII as a Mahayana Buddhist monastery and university. Unlike most Angkorian temples, Ta Prohm is in much the same condition in which it was found: the photogenic and atmospheric combination of trees growing out of the ruins and the jungle surroundings have made it one of Angkor's most popular temples with visitors. UNESCO inscribed Ta Prohm on the World Heritage List in 1992. Today, it is one of the most visited complexes in Cambodia’s Angkor region. The conservation and restoration of Ta Prohm is a partnership project of the Archaeological Survey of India and the APSARA (Authority for the Protection and Management of Angkor and the Region of Siem Reap).

Angkor Thom(Opens in a new window)

Angkor Thom (Central Khmer: អង្គរធំ; literally: "Great City"), located in present-day Cambodia, was the last and most enduring capital city of the Khmer empire. It was established in the late twelfth century by King Jayavarman VII. It covers an area of 9 km², within which are located several monuments from earlier eras as well as those established by Jayavarman and his successors. At the centre of the city is Jayavarman's state temple, the Bayon, with the other major sites clustered around the Victory Square immediately to the north.
