Luoyang Bridge
泉州, 福建
A stone sea-crossing bridge built in 1053, engineered with an oyster-shell foundation technique and later documented by Marco Polo.
为什么要去Luoyang Bridge？
As one of China's earliest large-scale stone sea bridges, it solved a genuine engineering problem — building stable piers on a shifting tidal seabed — using a solution (cultivating oyster beds to bind the stones) that was novel for its time.
怎么体验
Walk the full length of the bridge rather than viewing it from the shore; information panels along the way explain the construction technique.
小贴士
It's outside the old city centre, so plan for a taxi or bus rather than working it into a walking route with the other sites.
