What building, built around 1640, is generally considered to the the greatest architectural masterpiece to emerge from the Moghul empire?

This iconic white marble mausoleum, located in Agra, India, is the enduring symbol of the Moghul empire's architectural prowess. Commissioned in 1632 by Emperor Shah Jahan, its construction spanned over two decades, with the main structure completed around 1643. It was built as a final resting place for his most beloved wife, Mumtaz Mahal, who died during childbirth. The building is celebrated for its perfect symmetry, harmonious blend of Persian, Islamic, and Indian design elements, and stunningly intricate decorations, including delicate marble carvings and inlaid precious stones.

The story behind the monument is as grand as its design. Shah Jahan's profound grief fueled the creation of what many consider a monument to eternal love. To realize his vision, he sourced materials from across Asia, using over 1,000 elephants to transport everything from Chinese jade to Sri Lankan sapphire. Often described as "a teardrop on the cheek of time," the structure is a UNESCO World Heritage Site renowned for the way its appearance changes with the light. Its scale, emotional backstory, and breathtaking beauty cement its status as the pinnacle of Moghul artistic achievement.
