Kiran Joshi notes about Pierre Jeanneret's manhole covers: "Dotting 9000 acres of Chandigarh, these manhole covers, as a constant assertion of major elements of the Master Plan, have become the city's trademark. The design articulates Chandigarh's well-ordered road system, each residential sector, Le Corbusier's Capitol, the City Center and meandering edges of the Suhkna and Patiali-ki-Rao rivulets".
