Construction of the Taj Mahal
The construction of the Taj Mahal, one of the most iconic structures in the world, took around 22 years to complete. Here is a detailed explanation of the process:

Planning and Design
- The construction of the Taj Mahal was commissioned by Mughal Emperor Shah Jahan in memory of his beloved wife, Mumtaz Mahal.
- The design of the Taj Mahal was created by a team of architects led by Ustad Ahmad Lahauri, who incorporated elements of Persian, Islamic, and Indian architecture.

Foundation and Materials
- The construction of the Taj Mahal began in 1632 with the laying of the foundation.
- The main building material used was white marble sourced from Makrana in Rajasthan, India.
- Other materials such as precious and semi-precious stones, including lapis lazuli, jade, turquoise, sapphire, and coral, were used for intricate decorations.

Construction Process
- Skilled craftsmen and laborers were employed to work on the construction of the Taj Mahal.
- The construction process involved intricate carving, inlay work, and calligraphy on the marble walls and domes.
- The four minarets surrounding the main mausoleum were constructed leaning slightly outward to prevent them from falling onto the main structure in the event of an earthquake.

Completion and Inauguration
- The construction of the Taj Mahal was completed in 1653.
- The entire complex, including the gardens and reflecting pool, was finished in 1656.
- The Taj Mahal was officially inaugurated as a mausoleum and a symbol of eternal love.
The meticulous planning, skilled craftsmanship, and attention to detail that went into the construction of the Taj Mahal have made it a UNESCO World Heritage Site and a symbol of India's rich architectural heritage.
