The site of the famous Taga Fort, for instance, was a square nearly 3,000 feet on each side surrounded by an earthen wall over two miles long. Several administrative buildings on an elevation at the center of the site were enclosed within their own earthen wall, which measured 330 feet east to west and 390 feet north to south. Elsewhere within the site were other groups of buildings, including storehouses and what are thought to have been quarters for artisans and soldiers.' §REF§Shively, Donald H.  and  McCullough, William H.  2008.

Love, like Udong and Phnom Penh- the town s that succeeded it as the capital- was thoroughly international, with foreign quarters for Malay, Japanese, and Chinese traders (there were as many as 3,000 of the last in the 1540s). There Ang Chan (who really did exist) built a golden palace and at least four major wats, erecting a huge, four-faced Buddha of wood, the stone foundation of which survive in one of the town's vicars. The capital was fortified by earthen ramparts topped with palisades; these ramparts, which form a huge rectangle, are still visible.'§REF§(Coe 2003, pp. 208-209)§REF§"
