Rawalpindi is the 4th largest city of Pakistan. It is in Punjab province and located in Pothohar region of Pakistan. Rawalpindi is in the northernmost part of the Punjab province, 275 km (171 mi) to the north-west of Lahore.
The city has many old and new hospitals, universities and parks which made the city more important in terms of health from other cities. People came here from different cities for better facilities of their treatments.
Modern Rawalpindi is socially and economically intertwined with Islamabad, and the greater metropolitan area. The city is also home to numerous suburban housing developments that serve as bedroom-communities for workers in Islamabad. In June 2015, the Rawalpindi-Islamabad Metrobus, a new bus rapid transit line with various points in Islamabad, opened for service.
