ai in the 1980s, Dong was ed by a foreign company, but he quit the job in 2020 to found “Walking Geli Dong” guided walking tours of the city.
His fascination with manhole covers was triggered by a near-miss with a 1933 cover, which was lost to roadworks before he could take a photo of it.
“A manhole cover that’s still in use is a living piece of history,” Dong told Shanghai Daily. “There’s no need to replace it if it’s not broken. It stands as a symbol of urban life, allowing us to read and understand the city’s evolution.”
His collection of photos of old manhole covers has grown to more than 130 — and counting.
Dong considers them urban bookmarks. His photos include covers bearing insignias such as “S.T.C.” (former American Shanghai Telephone Co), “S.W.W.” (Shanghai Waterworks Co as it was known) and “C.M.F.” (erstwhile French Municipal Council).
His enthusiasm is shared by locals, foreign residents and visitors.
A German friend of Dong’s, inspired by the manholes, even hosted an art exhibition based on rubbings taken of the patterns on the covers.
Clarisse Le Guernic, a French expat living in Shanghai for nine years, operates a cultural agency that aims to expose foreign residents and visitors to the city’s deeper secrets. She looks at insignia like “S.M.C” (former Shanghai Municipal Council) and “P.W.D,” (former Public Works Department) and sees links to the city’s past.
“I just love anything related to history and every detail that can tell us more about it,” she told Shanghai Daily.
Among her cherished possessions are a manhole cover-style magnet she keeps on her fridge and a mobile phone holder bearing the pattern of one of Shanghai’s earliest manhole covers, which is now housed in the city’s history museum.
In areas like Nanjing Road E., the North Bund and the area around the iconic Normandie Apartments, more modern manhole covers have become canvases for artistic expression, with designs that celebrate local culture and history.
Cast-iron manhole covers adorning Nanjing Road Pedestrian Mall were crafted around 1999 as part of a street renovation project led by Zheng Shiling, a renowned local architect and then vice president of Tongji University.
Each of the 37 manhole covers features a landmark, such as the skyline of Lujiazui, the Yan’an Road Elevated Road, Shanghai Library, Shanghai Museum and the MidLake Pavilion in Yuyuan Garden.
Some 20 of these emblematic manhole covers remain in situ, while others were removed during renovation and extension of Nanjing Road E.
“By ‘engraving’ Shanghai’s most notable historical and modern buildings and urban landscapes on these manhole covers, we invite people to trace the city’s historical context,” said Zheng. “They help to enhance a sense of domain and place on this iconic street.”
Shanghai is not alone in adding artistic touches to mundane infrastructure. Globally, cities are transforming manhole covers into pieces of urban art, each telling a unique story of local heritage and culture.
Tokyo celebrates its pop culture with manhole covers featuring iconic anime and manga characters. Paris has painted manhole covers to resemble vinyl records. In the Norwegian city of Stavanger, decorative sewer lids on cobbled streets blend with the city’s quaint charm.
And in China, manhole covers near the Tsingtao brewery in the eastern city of Qingdao are embossed with motifs related to the famous beer brand.
Along Wuyi Road in Shanghai’s Changning District, manhole covers feature playful elements, including graffiti of cartoon characters like SpongeBob and Captain America’s shield. The initiative there, involving 40 artworks, is part of a broader effort to infuse the historical street with reminders of past culture and present-day innovation.
“Urban revamping should encompass more than just physical renovations; it’s also about embedding culture and humanity into our cityscapes,” said Zhang Chao, an artist leading the project.
He said the artistic manhole covers crafted by eight local artists not only beautify the area but also encourage the community to appreciate their local environment.
Manhole covers aren’t only artistic; they also can be “smart.” Many are equipped with high-tech sensors that help urban agencies monitor environmental data, including underground water levels. If data point to a problem, an alert is triggered and sensors pinpoint the exact location where maintenance crews should be dispatched.
From a technological standpoint, there is immense potential for smart manhole covers to contribute to Shanghai’s goal of a safe, efficient and eco-friendly environment, said Yu Diankun, a construction management staffer in the Hongkou District.
