Taj Mahal as one of the seven wonders of the world was constructed in 1631 and completed in 22 years. Twenty thousand people were deployed to work on it. The material was brought in from all over India and central Asia and it took a fleet of 1000 elephants to transport it to the site. It was designed by the Iranian architect Istad Usa and it is best appreciated when the architecture and its adornments are linked to the passion that inspired it. It is a "symbol of eternal love".
The Taj rises on a high red sandstone base topped by a huge white marble terrace on which rests the famous dome flanked by four tapering minarets. Within the dome lies the jewel-inlaid cenotaph of the queen. So exquisite is the workmanship that the Taj has been described as "having been designed by giants and finished by jewellers". The only asymmetrical object in the Taj is the casket of the emperor which was built beside the queen's as an afterthought.
The dome is made of white marble, but the tomb is set against the plain across the river and it is this background that works its magic of colours that, through their reflection, change the view of the Taj. The colours change at different hours of the day and during different seasons. Like a jewel, the Taj sparkles in moonlight when the semi-precious stones inlaid into the white marble on the main mausoleum catch the glow of the moon. The Taj is pinkish in the morning, milky white in the evening and golden when the moon shines.
