The northern gate of the Preah Khan temple inside the Angkor Archaeological Park was damaged on Friday when a 30-meter-tall tree was uprooted during a heavy rainstorm and came crashing down on the 12th century structure. The tree smashed through eight large stones that supported one of the ancient structure’s main gates, said Bun Narith, director-general of the Apsara Au*thority, a government body that manages the temples in the Angkor park complex. No one was injured by the falling tree, Mr. Narith said.
