By the 20th century, much of the temple had largely collapsed, and restoration efforts have since proven problematic: a first effort begun in 1960 was interrupted by the coming to power of the Khmer Rouge, and records of the positions of the stones were lost. A second attempt started in 1995 by a team of French-led archeologists as of 2005 was still ongoing, restricting visitor access. As of November 2010, partial visitor access was once again allowed, though not to the central structure. In April 2011, after 51 years, the archaeologists finished the restoration of the temple. King Norodom Sihamoni of Cambodia and Prime Minister Francois Fillon of France were among those who first toured the renovated temple during the inauguration ceremony on July 3, 2011.[1] [edit] References
