Ken Livingstone was joined by Bollywood and Big Brother star Shilpa Shetty for the launch of the three-month India Now festival of Indian culture.
"India is an emerging economic superpower and also has one of the world's most important cultures," says Mayor of London Ken Livingstone.
"The India Now season will be an opportunity to experience the richness of Indian culture and offers something for everyone. It will truly showcase the very best of modern Indian culture for to Londoners and visitors alike."
The season incorporates 1,500 events across London. Local highlights include the four-day Indomania festival at the Southbank Centre in September.
The Taj Mahal model has been created by Bollywood set designer Bijon das Gupta. It stands on a plinth hand-painted with modern Indian and London city scenes by Suchi Chidambaram.
The model travelled from Millbank to London Bridge on Tuesday morning and will be moored in front of the London Eye on Tuesday evening when the wheel will be lit with the colours of the Indian national flag.
The model will be taken to events across London as the India Now season continues.
"As an emerging market, India will be key to the ongoing success of the London Eye and we are looking forward to welcoming many Indian visitors in the future."
