Angkor Thom (Khmer: អង្គរធំ, ‘Great City’) is one of the largest of all Angkor cities. It was founded in the late 12th century CE by Jayavarman VII and remained the capital of the kingdom until the first half of the 15th century CE.
Jayavarman VII was crowned in 1181 after defeating the Chams, and decided to fortify his capital city to protect it against further attacks. The result was Angkor Thom, a walled city with a square layout, covering an area of nine square kilometres (3.5 square miles), surrounded by wide moats and a high laterite wall with five imposing gates.
Although the city walls enclose a number of large and important temples, it can be argued that Angkor Thom was designed as one giant temple, with the Bayon Temple as its central sanctuary.
