    The Taj Mahal (泰姬陵) is a love story, a sad and beautiful one. If it didn't exist, we would easily imagine

that the story of its construction was simply a fairy tale. Three hundred years ago, there lived an Indian

emperor called Shah Jahan. His wife was a beautiful and bright woman whom he loved greatly. Her title was

Mumtazl Mahan: its shortened form Taj Mahan, means "pride of the palace". In the year 1630 this beloved wife

of the emperor died. He was so brokenhearted that he thought of giving up his throne. He decided out of his

love for his wife, to build her the most beautiful tomb that had ever been seen.

    He called in the best artists and architects from India, Turkey, Persia and Arabia and finally, the design was

complete. It took more than twenty thousand men working over a period of 18 years to build the Taj Mahan,

one of the most beautiful buildings in the world.

    The building itself stands on a marble platform 29 meters square and 6-7 meters high. Towers rise from

each of the four corners. The Taj itself soars another 61 meters into the air. It is an eight-sided building made

of white marble.

    The emperor planned to build an identical tomb of black marble for himself on the other side of the river

connected by a silver bridge. However his son put him into a prison in the palace before he could finish, and

for the rest of his life, he could only gaze across river at the tomb of his beloved wife.
