The contrast between Old and New Delhi is striking. New Delhi spreads out with wide, tree-lined avenues and stately government buildings, while Old Delhi, historically known as Shahjahanabad, is a historic walled city of narrow streets and Mughal-era architecture. Founded by Shah Jahan in 1639, the city centres on the Red Fort, a massive red sandstone fortress that served as the Mughal emperors’ residence and administrative hub. Nearby, Jama Masjid rises with three domes and towering minarets, its courtyard capable of holding thousands of worshippers. From the mosque, Chandni Chowk extends as a labyrinth of streets where rickshaws weave between spice merchants, jewellers, and food vendors. Faded havelis, Jain and Hindu temples, the Sikh Gurudwara Sisganj, Khari Baoli’s spice market, and covered bazaars line the alleys.
