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.
Khlong Saen Saep
The Saen Saep Canal was built on the order of King Rama III during a conflict between Siam and Annam over Cambodia in order to establish water transport for soldiers and weapons. Construction began in 1837 and cost 96,000 Baht. Costurciton was finished in three years. Klong Saen Saep was once filled with lotus plants. King Mongkut in his fourth reign (1851-1868) built Sa Pathum Palace (Lotus Pond Palace) in Siam District. The name of the palace and present-day Pathum Wan District are derived from it.
