The diaolou on the right, from one of my relation's village, has remained in this precarious lean over the past 70+ years.
Like the leaning tower of Pisa, the soil conditions weren't just ready for such a heavy mass placed upon it. And seeing the pond in front of it, I would guess that the close proximity of water made soil conditions soft.
Thus, although the knowledge for reinforced concrete structures may have been available at the time, knowledge of soil conditions and geotechnical support may have been absent.
Nonetheless, this handsome structure has remained, watchful over it's tranquil surroundings - a beautiful structure, almost romantic in setting.
At the peak, the diaolou count numbered over 4,000 throughout Kaiping, and another thousand more throughout the neighbouring counties of Enping, Taishan and Xinhui.
There are now only 1,880 diaolou remaining. Many of them succumbing to the ravishes of time and nature ¡V weather, water and vegetative (chemical) erosion.
Initial building design, placement and planning perhaps determined a diaolou's longevity. Those with inadequate foundations, weak structures, etc. saw an early demise.
Other diaolou disappeared as villagers took them apart for building materials after the diaolou had served their original purpose.
