Most people understandably prefer not to stay very long in Agra, as it's a rather unappealing city with a lot of touts. However, there are quite a few worthwhile places to visit in Agra and around, apart from India's most famous monument -- the Taj Mahal. The many interesting remnants of the Mughal era (predating the Taj Mahal) will surprise you and the crazy, congested bazaars of the Old City will fascinate you. It's possible to experience village life and get close to nature as well.
This UNESCO Word Heritage site is one of the most robust and important Mughal forts in India. After arriving in Agra in 1558, Emperor Akbar extensively rebuilt the fort using red sandstone. The process took eight years and was completed in 1573. The fort retained its stature until Shah Jahan shifted the Mughal capital from Agra to Delhi in 1638. It lost much of its grandeur after his death in 1666, and during the 18th century was repetitively invaded and captured. Finally, it fell into the hands of the British in 1803.
