The Chinese city of Nanjing has recovered about 80,000 lost bricks for its ancient city wall after one year of the launching of a reclaiming campaign.
The construction of the City Wall of Nanjing started in 1366 and was completed in 1393. Some 350 million bricks had been laid by 280,000 workers from 152 counties in five provinces.
However, a lot of bricks were lost after some sections of the city wall had been destroyed due to historical reasons. Some of the lost bricks were treated as construction waste, while others were used by local citizens for the construction of their own houses.
In order to recover the lost bricks, related local departments launched a campaign last year encouraging citizens to return them. People who offer valuable information can also get a cash reward.
About 80,000 bricks have been recovered so far.
