In the last five years, major work has been undertaken to preserve the Angkor monuments and improve the experience for visitors.
Work on the western causeway has been going on for years. It is nearing completion, with 75 percent of the paving now complete. Works are going on in the central area of the third (top level) of Angkor Wat, including the central tower. New stairs have been built to allow safer access, but the area is not yet open to the public.
The famed Churning of The Sea of Milk gallery of bas reliefs is being renovated to prevent water damage. This work will continue until 2010, with most of the reliefs still viewable. A large display board shows an impressive photomontage of the reliefs.
