Located in Mangaru Village, Chanam County, Shannan Prefecture, this manor was very typical of those in rural areas of old Tibet in architectural style and scale. The manor owner owned 142 household serfs. Who was the owner of Namseling Manor? Legend has it that the original owner was the son-in-law of the last Tsampo Nammar of the Tubo kingdom. His descendents, inheriting the aristocratic title for generations, were officials in Lhasa.

It is said that this manor was built according to the pattern of the "Residence of the God of Wealth" in Buddhism. The towering main building was sited on the southern bank of the Brahmaputra River.

Two layers of walls are built around the manor. With the rocks as the foundation and rammed earth as the main walls; the rectangular outer walls were narrow and short and the inner walls were also based on rocks. The foot of the inner walls was about 4.5 meters wide, and body of wall was made of rammed earth. The width of the inner walls tended to become narrow towards the top. The top, two meters in width, had wooden eaves to prevent the rain from eroding the wall. The inner walls were square and ten meters or so tall. Simple blockhouses were built at the four corners of the inner walls. The main three-meter-wide entrance door was located on the middle of the east wall. A small door opened on the east part of the southern wall. A watchtower was set up on the top of the middle part of the western wall. Standing on the roof of the watchtower, one gained a general view of the manor and croplands. The chamberlain of the manor owner often stood on the roof of the watchtower to supervise the labor of the serfs. Between the outer and inner walls was dug a five-meter-wide dyke (moat), with its walls built of stones. The main building stood on the north-middle part of the manor, facing south. The seven-storied or 22-meter-tall building was built of earth and stone. Before the door of the building there was a rectangular area with steps to the upper stories. The ground floor was used as a livestock pen and prison, the first to fourth stories were offices, guest rooms, sutra hall and kitchen, the fifth story formed the Lhazhor Lhakang hall, on the walls of which were mural paintings such as figures of Sakyamuni, Amitabha Buddha and the Buddhist Guardian. The eastern part of the sixth story, with a sunny exposure, served as the bedroom of the manor owner, while small sutra halls lay in the western part. The seventh story housed the living room and family hall for worshipping Buddha. On the southern part of the manor was a picturesque garden called "Lingka" in Tibetan. In the garden grew apples, peaches, walnuts, poplars and other trees. There were stretches of green lawn on both sides of the roads, decorated with flowers. In summer, the family came for fun here.
