Tongwan City in Nomadic Times
Hun Capital Rises from the Sands of
Time
Tongwan City, extending to nearly 20,000 square kilometers,
has lain buried beneath the desert sands for more than 1,000 years. The city was
laid out on an east-west axis and consisted of an outer city, an inner city, and
a palace city.
The outer city was where ordinary folks lived. Government offices and the
residences of the nobility were located in the inner city. Inside the palace
city was the inner sanctuary of the imperial city where Helianbobo himself
lived.
Historical records suggest that by the year 431, Tongwan City and its
hinterland supported a population of over 40,000 Hun nomads and Han farmers. By
984 however, the city had been abandoned, and would later become buried under
the shifting sands.
"Tongwan City was built on the natural contours of the ground and so is
higher in the northwest and lower in the southeast. This served to provide a
measure of protection against the cold winter winds. Meanwhile, the river in the
north of the city could easily be channeled to supply water to the residents or
used for the city moat," said Dai Yingxin, a famous archaeologist who has been
engaged in field investigation and trial digs at the site for years.
"The city wall was constructed in layers by ramming a mix of cohesive white
clay and sand bound together with glutinous rice gruel and slaked lime. The
western section is 16 to 30 meters thick. This type of rammed earth construction
has proven to be almost as strong and resistant to erosion as stone masonry,"
Dai said.
