Montreal Underground city and Over ground city – Double Decker City
Montreal is the Second largest city in Canada and the largest city in the province of Quebec. The name Montreal has been taken from Mont-Royal which is the triple peaked hill located in the heart of the city.
Montreal is also the world’s largest underground complex in the world. It is also known as the indoor city. Montreal is the network of interconnected complexes underground. But entire city is not underground. There are certain parts which are overground. Since Montreal has both overground city complex as well as underground city complex, it is popularly known as “Double Decker City” or “Two Cities in One”. The interconnections between different complexes that are underground has been achieved through the construction of tunnels. The tunnels are technically and architecturally sound. They have conditioned air and good lighting to create comfortable environment and make it aesthetically pleasing.
