The complex Tai Mahal was built between 1631 and 1648. It was built by about 20 thousand workers. The building has been built from the white marble and combines Persian, Turkish, Indian and Islamic architectural styles. The surface is decorated with semiprecious stones, precious stones and the calligraphic decoration in black marble. The main architect of the building was the architect Ustad Ahmad Lahauri.
The Tai Mahal is a pearl of Muslim art. In 1983 it was inscribed in the UNESCO List of World Heritage Site. On 7 July 2007 Tai Mahal was listed among the new 7 wonders of the world. Sadly, due to air pollution Tai Mahal changes its colour into yellowish and loses its original gleam. An Indian government's commission suggested that the entire building would be coated with mud, which then will be left to dry and washed down. When mud gets drying, it catches and carries away the dirt.
