Standing proudly along the Yamuna River, Delhi's Red Fort—known historically as Qila-i-Mubarak or the Blessed Fort—remains one of the most striking symbols of imperial India. Commissioned during the height of the Mughal Empire, this sprawling citadel represents a masterclass in architectural engineering, political strategy, and cultural synthesis. If you've ever wondered who built it, why it was constructed, and how it shaped centuries of South Asian history, the answers lie in a 17th-century royal relocation that changed Delhi forever.
The Red Fort was built by the fifth Mughal emperor, Shah Jahan, between 1638 and 1648. Shah Jahan constructed the fortress-palace as the core of his new capital city, Shahjahanabad, after deciding to shift the imperial seat of power from Agra to Delhi. Designed by the visionary architect Ustad Ahmad Lahauri—who also conceptualized the Taj Mahal—the complex merges Persian, Timurid, and Hindu architectural traditions into what historians call the Shahjahani style.
Why Shah Jahan Built a New Capital in Delhi
By the late 1630s, Agra had served as the beating heart of the Mughal Empire for decades, but Shah Jahan envisioned a grander stage for his dynasty. He wanted a capital city that offered better control over trade routes, abundant water access from the Yamuna River, and a fresh canvas to display his architectural ambitions.
Shahjahanabad was planned as a fortified city complete with grand avenues, bustling bazaars, majestic mosques like the Jama Masjid, and a central citadel that would house the imperial court. The Red Fort served dual purposes: it was an impenetrable defensive fortress and an opulent royal residence meant to project absolute sovereign authority.

The Construction Timeline and Costs
Planning for the fortress began in May 1638, aligning with auspicious astrological and religious dates. Construction took roughly nine years, with the official inauguration taking place in April 1648.
- Labor Force: Thousands of stonemasons, artisans, laborers, and engineers worked under imperial oversight.
- Estimated Cost: Historical records suggest the initial construction cost approximately 60 lakh (6 million) rupees.
- Materials: While the iconic red sandstone forms the massive outer defensive walls—giving the fort its modern name—pure white marble was heavily utilized inside for imperial halls and private chambers.
Architectural Layout and Key Structures
The fort's layout follows a strict geometric grid, organized around a central axis that transitions from public zones to intensely private royal quarters. The massive enclosing walls stretch for over two kilometers, varying in height to adapt to the terrain and integrate the older Salimgarh Fort.
The Main Entrances and Chhatta Chowk
Visitors traditionally approach the complex through the Lahori Gate, the western entrance facing Lahore. Beyond this gate lies the Chhatta Chowk (Covered Bazaar), an innovative vaulted arcade where royal merchants once sold silk, jewelry, and precious gems to the court.
Public and Private Audience Halls
The interior spaces reflect the strict ceremonial hierarchy of the Mughal court:
- Diwan-i-Am (Hall of Public Audience): A large pillared hall where the emperor listened to public grievances and addressed common subjects.
- Diwan-i-Khas (Hall of Private Audience): An exquisitely carved marble pavilion where the emperor met ministers and foreign dignitaries. This hall once housed the legendary Peacock Throne before it was plundered.
Political Decline and Post-Mughal Transformations
The Red Fort witnessed the gradual decline of the Mughal Empire following Aurangzeb’s reign. In 1739, the Persian ruler Nadir Shah invaded Delhi, breaching the fort, slaughtering inhabitants, and carrying off immense treasures, including the Peacock Throne and the Koh-i-Noor diamond.
By the early 19th century, the Mughal emperors were nominal rulers under the shadow of the British East India Company. Following the Indian Rebellion of 1857, British forces seized the fort, turning it into a military garrison. During this occupation, the British demolished significant portions of the inner residential palaces, replacing them with bleak European-style barracks.
Modern Significance and Heritage Status
In the 20th century, the fort transformed from a symbol of colonial suppression into a stage for national liberation. The historic Red Fort Trials of 1945–1946 galvanized public support for Indian independence.
On August 15, 1947, India gained independence, and Prime Minister Jawaharlal Nehru raised the national flag above the Lahori Gate—a tradition that continues every Independence Day. Designated as a UNESCO World Heritage Site in 2007, the fort now houses multiple museums dedicated to Archaeological Survey of India preservation efforts, war memorials, and the complex history of South Asia.
Frequently Asked Questions
Why is the fort called the Red Fort if it was originally white?
Historical records indicate that parts of the fort's original sandstone masonry were coated with lime plaster or painted in red and white patterns. Over centuries of weathering, the plaster peeled away, leaving the exposed red sandstone that defines its modern appearance.
Did Ustad Ahmad Lahauri design both the Taj Mahal and the Red Fort?
Yes. Architectural historians attribute the conceptual blueprint of both iconic monuments to Ustad Ahmad Lahauri, reflecting the pinnacle of Shah Jahan's centralized architectural patronage.
What happened to the inner royal palaces built by Shah Jahan?
Many of the original marble pavilions, private gardens, and imperial apartments survived the transition of power, but approximately eighty percent of the structures inside were destroyed by the British military after 1857 to construct functional barracks.
Can visitors explore the entire Red Fort complex today?
While large portions of the gardens, museums, and grand audience halls are open to the public, certain zones remain restricted due to ongoing conservation work and military occupancy in select perimeter sections.
