Explanation: Mohenjo-Daro, one of the largest cities of the Indus Valley Civilization, is renowned for its advanced urban planning and construction techniques. The city, located in present-day Pakistan, was built around 2600 BCE and was a major center of the Indus Valley Civilization, which flourished between 3300 BCE and 1300 BCE.
One of the most remarkable features of Mohenjo-Daro is the exactness and standardization of the measurements used in its construction. The Indus Valley Civilization demonstrated a high level of precision in their construction techniques, which is evident in the uniformity of the bricks and the layout of the city. The bricks used in the construction of Mohenjo-Daro were standardized to a ratio of 1:2:4, which means that the length of the brick was twice its width, and four times its height. This standardization allowed for efficient construction and ensured that the buildings were structurally sound.
The city was laid out in a grid pattern, with streets aligned in a north-south and east-west direction. This layout indicates a high level of organization and planning, as the city planners had to consider the orientation of the streets to ensure proper drainage and ventilation. The streets were also wide enough to accommodate wheeled carts, which suggests that the city had a well-developed transportation system.
In addition to the standardization of measurements, Mohenjo-Daro also had a sophisticated drainage system, public baths, and granaries. The drainage system was designed to collect and channel rainwater and sewage away from the city, which helped to prevent the spread of disease. The public baths, known as the Great Bath, were large structures that were used for religious and social purposes. The granaries were used to store grain and other food items, which were essential for the survival of the city's population.
The exactness of the measurements used in the construction of Mohenjo-Daro reflects the advanced urban planning and engineering skills of the Indus Valley Civilization. The standardization of construction techniques and the well-planned layout of the city demonstrate the sophistication of the civilization and its ability to create a functional and efficient urban environment. This level of precision and organization is a testament to the advanced knowledge and skills of the people who built Mohenjo-Daro, and it continues to fascinate archaeologists and historians to this day.
