Preserving Urban Memory: The Hidden Street Artifacts of Old Saigon

     History is not just found in grand monuments, majestic palaces, or towering skyscrapers. Sometimes, the most precious memories of a city are hidden right on the sidewalks, at street corners, on mossy walls, or even right beneath our feet.

As you walk through Ho Chi Minh City, if you pause and look closely at the mundane objects of the streetscape, you will discover that Saigon is a living museum.

1. The Century-Old Cast Iron Manhole Covers

Every day, millions of people step over the iron and cement manhole covers scattered across Saigon's streets. Most are modern and plain, but a few have quietly survived across three centuries.

The 1878 "Sở Pháo Thủ" Relics

If you explore the restricted courtyard of the Notre-Dame Cathedral Basilica of Saigon (currently under major renovation), you can find a massive cast-iron manhole cover measuring 1.2m x 1.2m.

Embedded into the blue stone curb near the side gate facing the Central Post Office, this cover bears the crisp, rust-free inscription: "Saigon Direction de l'Artillerie 1878".

• The Weight of History: These French-era cast-iron covers weigh around 140kg (compared to just 80kg for modern ones).
• The Origin: Direction de l'Artillerie was known to old Saigonese as the "Artillery Department" (Sở Pháo Thủ), located within the historic Ba Son Shipyard. The skilled metallurgy workers of Ba Son cast these civic pieces alongside military armaments.

Where to Find Them Today:

• Notre-Dame Cathedral: Two identical 1878 covers (one near the gate, one facing the park).
• Independence Palace: Outside the fence at the intersection of Nam Ky Khoi Nghia and Nguyen Thi Minh Khai.
• Ben Thanh Market: Near the North Gate sits another 1878 cover—making it older than the market building itself (which opened in 1914).
• Ham Nghi Boulevard: At the top of the street, though the year has faded over time.
• Ky Hoa Street (District 5): Four cast-iron covers stamped with "Ville de Cholon", marking the boundary of the historic twin city of Cholon

2. The Unsung Monuments: Historic Water Towers

Clean water and modern sewage systems are the foundational blocks of any civilized city. In Saigon, the quest for clean water left behind striking architectural landmarks.

The Sawaco Heritage Tower

The site of the first modern water treatment system was the International Square, famously known today as Turtle Lake (Hồ Con Rùa). The central tower in the lake replaced an original French water tower built in 1878.

However, its "younger sibling"—built in 1886—still stands beautifully preserved within the headquarters of the Saigon Water Corporation (SAWACO). Peeking through the green canopy, its massive black steel tanks and conical corrugated roof look like a traditional Vietnamese conical hat (nón lá), serving as a rare 19th-century "technological monument."

3. The Mysterious Grey "Power Boxes"

Scattered around alley entrances and street corners are small, unassuming concrete structures with thick, locked iron doors painted in faded grey. For generations, Saigonese children were warned by their parents: "Don't go near them, you'll get electrocuted!"

These are historic electrical transformers. If you look closely at the iron doors, you will see letters stamped inside a circle: CEE or SĐL, followed by a year.

• CEE: Compagnie des Eaux et d'Électricité de l'Indochine (The French Indochina Water and Electricity Company).
• SĐL: Sài Gòn Điện lực Công ty (The Saigon Electricity Company, which later succeeded CEE).

Living Time Capsules of 1959:

• Under the foot of Cong Ly Bridge (overlooking Vinh Nghiem Pagoda).
• In the basement of the Saigon Opera House (directly across from the Caravelle Hotel).
• In front of An Dong Market on An Duong Vương Street.

Even the operational names of these stations reflect history, such as the Quốc Hội Station (at the Opera House, which once served as the National Assembly building) and the Quan Thuế Station (at the historic Customs Directorate).

Conclusion: Why We Must Protect Street Antiquities

From old fire hydrants near Kim Bien Market to colonial-era lampposts at the intersection of An Duong Vuong and Ngo Quyền, Saigon's streets are filled with historical clues.

As Ho Chi Minh City modernizes at a rapid pace, these street artifacts risk being lost to scrap metal yards, theft, or urban clearance. Transforming these items into open-air museum pieces—much like how Hanoi revitalized the Hang Dau Water Tower—is essential to ensuring that the city does not lose its collective memory.

Next time you take a walk or a motorbike ride through District 1 or District 5, look down at the sidewalks and look closely at the corners. History is waiting to be read.
