The Baphoun temple (Khmer: ប្រាសាទបាពួន)is a temple at Angkor,Cambodia.It is located in Angkor Thom,northwest of the Bayon.Built in the mid-11th century,it is a three-tiered temple mountaion built as the state temple of Udayadityavarman II dedicated to the Hindu God Shiva.It is the archetype of the Baphoun style.The temple adjoins the southern enclosure of the royal palace and measures 120 meters east-west by 100 meters north-south at its base and stands 34 meters tall withou its tower,which would have made it roughly 50 meters tall.Its appearance apparently impressed Emperor Chengzong of Yuan China's late 13th century envoy Chou Ta-Kuan during his visit from 1296 to 1297,who said it was the Tower of Bronze ... a truly astonishing spectacle,with more than ten chamber at its base,in the late 15th century,the Baphoun was converted to a Buddhist temple.A 9 meters tall by 70 meters long statue of a recling Buddha was built on the west side's second level,which probaly required the demolition of the 8 meters towers above, thus explaining its current absence.The temple was built on land filled with sand,and due to its immense size the site was  unstable throughout its history.Large portions had probably already collapsed by the time the Buddha was added.By the 20th century,much of th 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 th Khmer Rouge,and records of the position of the stones were lost. a second attempt started in 1995 by a team of French-led archeologists as of 2005 was still on going,resticting visitor access.As of November 2010,partial vistor access was once again allowed,though not to the central structure.

In April 2011,after 51yeays,the archaeologists finished the restoration of the temple.King Norodom Shiamoni of Cambodia and Prime Minister Francors Fillon of France were among those who first toured the renovated temple during the inauguration ceremony on July,32011.
