Old Delhi is a culinary, architectural, and historical adventure. Start at the Red Fort, a sandstone fortress that covers nearly 255 acres. Consider returning in the evening when the fort comes alive with a sound-and-light show that recreates 5,000 years of India's history. Next, continue to Jama Masjid, the largest mosque in India, which was commissioned by Shah Jahan—the same emperor who built the iconic Taj Mahal. Step outside the gates and enter Chandni Chowk, which is touted as the oldest and busiest street market in Delhi. Chandni Chowk hosts an impressive mix of shops that specialize in goods such as silk, silver, crafts, spices, and leather products. Find renowned restaurants, food stands, and sweet shops—including the original Haldiram’s, Meghraj and Sons, Bikaner Sweet Shop, and Ghantewala Halwai. The street also houses several different religious shrines that illustrate a genuine cultural harmony: Sri Digambar Jain Lal Mandir and Bird Sanctuary, Gauri Shankar Hindu Temple, Sikh Gurdwara Sis Ganj Sahib, and Central Baptist Church. You'll also find historic private residences nestled amid a labyrinth of small streets and neighborhoods around Chandni Chowk.
