Zhouzhuang, an ancient town in China, is known for its well-preserved architecture and waterways. It has many stone bridges and water lanes laid out in a grid-like pattern. Notable historic structures include the Twin Bridges from the 16th century and the grand mansions of Shen's House from 1742 and Zhang's House from the 15th century, which demonstrate traditional Chinese architectural styles. Zhouzhuang was an important economic and cultural center due to its extensive canal network, and it retains much of its historic character today thanks to over 60% of original buildings still standing.
