Angkor Wat
Angkor Wat (; , "Capital Temple") is a temple complex in Cambodia and one of the largest
religious monuments in the world, on a site measuring . Originally constructed as a Hindu temple dedicated to the god Vishnu for the Khmer Empire, it was gradually transformed 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 (, 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.
Royal Palace, Phnom Penh
The establishment of the Royal Palace in Phnom Penh in 1866 is a comparatively recent event in the history of the Khmer and Cambodia. The seat of Khmer power in the region rested in or near Angkor north of the Great Tonle Sap Lake from 802 AD until the early 15th century. After the Khmer court moved from Angkor in the 15th century after destroyed by Siam, it first settled in Phnom Penh which back then named as "Krong Chatomok Serei Mongkol" () in 1434 (or 1446) and stayed for some decades, but by 1494 had moved on to Basan, and later Longvek and then Oudong. The capital did not return to Phnom Penh until the 19th century and there is no record or remnants of any Royal Palace in Phnom Penh prior to the 19th century. In 1813, "King Ang Chan" (1796–1834) constructed Banteay Kev (the 'Crystal Citadel') on the site of the current Royal Palace and stayed there very briefly before moving to Oudong. Banteay Kev was burned in 1834 when the retreating Siamese army razed Phnom Penh. It was not until after the implementation of the French Protectorate in Cambodia in 1863 that the capital was moved from Oudong to Phnom Penh, and the current Royal Palace was founded and constructed.
