Delhi

Delhi is not one city but many — seven, by traditional reckoning, each built upon the ruins of its predecessor over three thousand years of continuous habitation. The Mughals built their red-sandstone fortress and marble mosques here; the British raised a neoclassical imperial capital on the plains to the south; and modern India has layered its own chaotic, vibrant, twenty-first-century metropolis atop it all. To arrive in Delhi is to step into a palimpsest of civilizations, where a twelfth-century minaret stands within sight of a twenty-first-century metro station, and a Mughal emperor's tomb garden serves as the neighborhood park for families flying kites on a Sunday afternoon.

Old Delhi, the walled city built by Mughal Emperor Shah Jahan in the seventeenth century, is a sensory avalanche. Chandni Chowk, the main bazaar street, pulses with cycle rickshaws, spice merchants, silk traders, and street-food vendors in a scene that has barely changed in four hundred years — minus the motorcycles. The Red Fort, Shah Jahan's vast sandstone citadel from which the Prime Minister addresses the nation each Independence Day, anchors the northern end. Jama Masjid, India's largest mosque, presides over the southern end with a gravitas that silences even the most jaded traveler. Between them, the lanes of Kinari Bazaar, Dariba Kalan (the jewelers' market), and the spice market of Khari Baoli deliver sensory experiences that no mall or department store on Earth can replicate.

Delhi's culinary scene is arguably the most diverse and dynamic of any city in India. The city's Mughal heritage lives on in the kebab shops and biryani houses of Old Delhi, where seekh kebabs are grilled over charcoal and nihari — a slow-cooked stew of bone marrow and spices — has been served for breakfast since the reign of the Mughal emperors. Street food is Delhi's religion: chaat (tangy snack mixtures of fried dough, chickpeas, yogurt, and chutneys), paranthas (stuffed flatbreads) from the famous Paranthe Wali Gali, and kulfi (dense, cardamom-scented ice cream) from carts in every neighborhood. Modern Delhi has also embraced fine dining with gusto — restaurants like Indian Accent have redefined Indian cuisine for a global audience, while Dilli Haat food market offers regional specialties from all twenty-eight states under one roof.

New Delhi, designed by Edwin Lutyens and Herbert Baker in the 1910s and 1920s, presents a strikingly different face. Rajpath (now Kartavya Path), the grand ceremonial boulevard, stretches from Rashtrapati Bhavan (the President's House) to India Gate, a war memorial arch that anchors the city's geometric plan. Humayun's Tomb, a sixteenth-century Mughal garden tomb that directly inspired the Taj Mahal, is a UNESCO World Heritage Site of breathtaking beauty. The Qutub Minar, a 72.5-meter sandstone tower built in the twelfth century, marks the site of Delhi's first Muslim settlement. And Lodhi Gardens, a serene park dotted with fifteenth-century tombs of the Sayyid and Lodi dynasties, offers a green escape where joggers and families coexist with seven centuries of history.

Uniworld River Cruises includes Delhi on its India itineraries as a pre- or post-cruise extension, with the city serving as the gateway to northern India's cultural treasures. The Taj Mahal in Agra, Jaipur's pink-walled palaces, and the holy city of Varanasi are all accessible from Delhi by train or short flight. The best time to visit is October through March, when the scorching summer heat has dissipated and the city enjoys cool, clear weather perfect for exploring its monuments and markets.
