The APSARA Authority reports that the damage to Angkor Thom from the 2011 typhoon has been repaired.

Angkor Thom restoration complete
Phnom Penh Post, 28 December 2015
Major restoration works have been completed at the former seat of power of the Angkorian civilisation, Angkor Thom, following damage inflicted to the site by Typhoon Nesat in 2011.
Funded and implemented by the Apsara Authority, the project began last year to repair damage to the 12-kilometre outer wall of the enclosure that neighbours Angkor Wat and was the last and most enduring capital of the Khmer Empire.
“Angkor Thom was the centre of the Cambodian empire for 500 years, so restoring it was extremely significant,” said Long Kosal, an Apsara spokesman.
While Angkor Wat remained unscathed, Typhoon Nesat saw many parts of Angkor Thom submerged, bringing down the walls of the 12th-century site and threatening other structures. “The impact of the collapse was very strong, so it was urgent to repair the wall so that no further damage was caused,” Kosal said.
