A manhole cover is a removable lid over an opening to a man-made hole large enough for a person to pass through i.e. a manhole. For security reasons a cover keeps unauthorised people out and for safety reasons it prevents anyone (or anything) from falling in. These types of covers are typically used to safely and securely restrict entry to foul and surface water drainage systems, and other underground chambers, that require worker access for maintenance purposes. They are often made from cast iron, ductile iron, galvanised steel, concrete or even a combination of several of the above.
The design of manhole covers extends beyond mere functionality; it also embodies local culture and artistry. Many cities have adopted unique designs that reflect their heritage or historical significance. For instance, in cities like Paris, manhole covers are imprinted with artistic motifs that celebrate the city's artistic legacy. Similarly, New York City’s manhole covers are often adorned with the initials of the utility companies responsible for their maintenance. These artistic elements serve as a reminder that even the most basic urban fixtures can contribute to the character of a city.
