The "Bridge within a Bridge" is a scenic attraction created by two ancient bridges, the Tongji Bridge which crosses the river from east to west and the Renji Bridge running from south to north that joins the former at one end. Either of two bridges can be seen through the arch of the other, hence the name. Having been rebuilt five times, Tongji Bridge is a 28.4 meters (93 ft) and 3.5 meters (11 ft) one-curvature arch bridge, with a span of 11.8 meters (39 ft). Renji Bridge, which has also undergone repairs during its history, has a length of 22.6 meters (74 ft), a width of 2.8 meters (9.2 ft) and a span of 8.5 meters (28 ft).
Wuzhen is divided into six districts. These are: the traditional workshops district, the traditional local-styled dwelling houses district, the traditional culture district, the traditional food and beverage district, the traditional shops and stores district, and the water township customs and life district. Following an east-west-east circuit created by these six districts, visitors can witness reenactment of traditional practices and cultures.
