Two ancient towns, both more than 1,800 years old, have been discovered under Qiandao Lake in East China's Zhejiang Province.

After a preliminary investigation, experts believe they might be the biggest ancient buildings ever found in perfect condition in China.

Located near the Xin'an River, Chun'an and Sui'an started as counties in the Eastern Han Dynasty (AD 25-220). The two towns were buried 40 years ago to make way for a reservoir.

Historical records show that the two towns adopted architectural styles using bricks, wood, stones and tiles.

A dozen trial dives led to the discovery of the town of Sui'an. An underwater camera has recorded the whole process of finding the ancient complex.

According to the tape, the 3-metre high ancient town wall is 30 metres under water. Nails and door knockers are visible on the wall gate. A house stands perfectly though algae has covered its walls and wooden window frames. Inside, the wooden staircase and furniture is still present and the fine wood engravings indicates the former prosperity of the town.
