A NEW CAPITAL

When the new state of Pakistan was founded in 1947, Karachi acted as the capital city. However, it was difficult for Karachi to remain in this role due to a number of drawbacks such as the climate and the state of the existing buildings. Rather than try to overcome these drawbacks, the government decided to create a new capital city. In 1959, a commission was established to investigate the possible locations of this new city. The advisor appointed to the commission was Dr Doxiadis, a famous architect and city planner.

Dr Doxiadis and his colleagues looked at the various locations. They then produced a report suggesting two possible areas: one just outside Karachi and the other to the north of Rawalpindi. Both locations had advantages as well as disadvantages. Which site was it to be?

The choice between these two options was made after consideration of many factors, such as transportation, the availability of water, economic factors, and factors of national interest. Finally, the site north of Rawalpindi was chosen and on the 24th February 1960, the new capital was given the name of ‘Islamabad’ and a master plan was drawn up. This master plan divided the area into three different sections: Islamabad itself, neighboring Rawalpindi, and the national park.

Each of these three sections had a different role. Islamabad would act as the nation's capital and would serve its administrative and cultural needs, whereas Rawalpindi would remain the regional center with industry and commerce. The third piece of the plan, the national park, was planned to provide space for education, recreation, and agriculture.

Today Islamabad is a thriving city of about 1 million people. It offers a healthy, pollution-free atmosphere, plenty of water, and many green spaces. Guide tree-lined streets, elegant public buildings, and well-organized bazaars and shopping centers. The new capital is a superb example of good urban planning.
