The May Thirtieth Movement Monument is an outdoor sculpture and memorial commemorating to the May Thirtieth movement, installed at People's Park in Shanghai, China.

The steel sculpture was installed just south of Nanjing Road in the 1990s.

Behind the sculpture is a bas relief explaining, in Chinese, the events that took place in 1925.

The city's homeless population apparently fails to grasp the monument's historical richness and instead tend to use its relative seclusion to literally take a piss on their shared heritage.

But, in the spirit of the monument, it's kind of fitting the way underclasses are making their voices heard.
