Old town Delhi.
Old Delhi or Purani Dilli was founded as a walled city of Delhi, India, founded as Shahjahanabad in 1639, when Shah Jahan, the Mughal emperor at the time, decided to shift the Mughal capital from Agra. The construction of the city was completed in 1648, and it remained the capital of the Mughal Empire until its fall in 1857, when the British Raj took over a paramount power in India. It was once filled with mansions of nobles and members of the royal court, along with elegant mosques and gardens. Today, despite having become extremely crowded and dilapidated, it still serves as the symbolic heart of metropolitan Delhi.
