<P> As of 2006 the monastery had 400 monks, and the number was reported to be 450 in 2010 . Tawang Manuscript Conservation Centre was established in the monastery in August 2006, which has curated 200 manuscripts, and 31 manuscripts have been treated for preservation . In November 2010, it was reported that the monastery was threatened by a risk of landslide, with The Times of India reporting "massive landslides around it". Professor Dave Petley of Durham University in the United Kingdom (UK), an acknowledged landslide expert, wrote: "the northern flank of the site appears to consist of a landslide scarp...The reasons for this are clear--the river, which flows towards the south, is eroding the toe of the slope due to the site being on the outside of the bend . In the long term, erosion at the toe will need to be prevented if the site is to be preserved ." </P> <P> The monastery currently has control over 17 gompas in West Kameng district . The monastery has administrative control over two dzongs, each headed by a monk; the Darana Dzong built in 1831 and the Sanglem Dzong, also known as Talung Gompa, in the south - west part of Kameng district . These dzongs not only collect taxes but also preach Buddhism to the Monpas and Sherdukpens of Kameng . The monastery owns cultivable lands in the villages of Soma and Nerguit and a few patches in some other villages which are tilled and cultivated by farmers, who share the produce with the monastery . The present resident head of the monastery is the incarnate Gyalsy Rinpochey . </P> <P> At the entrance to the monastery there is colourful gate structure, known as the Kakaling, which is built in the shape of a "hut - like structure", with side walls built of stone masonry . The roof of the Kakaling features mandalas, while the interior walls have murals of divinities and saints painted on them . A distinctive mural, the ninth mural from the southwest west corner of the southern wall, is of Ningmecahn, the protector deity of the Bon religion, who is considered the guardian deity of the Tawang region . Ahead of the main gate of the Kakaling, to its south, is another entry, an open gate . </P> <P> The main entrance to the monastery, to the south of the open gate, has massive doors fitted on the northern wall . This outer wall is 925 feet (282 m) in length, with heights varying from about 10--20 feet (3.0--6.1 m). Apart from the main gate, the southern side of the monastery has another entry gate, which also has a massive door . Nearer to the gate, there are two small openings in the wall which provide the complete view of the exterior part of the eastern wall that connects to the Kakaling . According to a legend, the 5th Dalai Lama had given a roll of thread to be bound around the walls of the monastery to denote the extent to which the monastery should be built . </P>
