#7. Yu Yuan Garden -- In the center of Old Town, just southwest of the Bund, the Garden of Peace and Comfort offers an escape from the fast pace of the surrounding city. With 30 pavilions and over 5 acres, this 16th century garden can be explored for days. Of the many temples and halls, the Grand Rockery is the most popular. Two thousand tons of rare yellow stones are combined with rice glue to form a massive sculpture that stands 46 feet high.
