Guangfulin Park is a heritage site near Songjiang University. Because of its enormous size and ongoing excavation, only certain phases have been opened to tourists. One of the most popular spots is the Guangfulin Cultural Exhibition Hall as it appears to be a dome 'floating' on the Fulin Lake, and its exhibition space is mostly underground (or underwater, really). You can visit its many exhibition halls and museums which contain artefacts believed to be from the Late Stone Age to Zhou Dynasty.
