2. EXPLORE THE RED FORT If there ever were a fortification that can be a symbol of Indian history, it would be the Red Fort aka Lal Qila. Stories of triumph and defeat, glory and conspiracy are etched in every corner of this red sandstone and marble complex built by Shah Jahan in 1639. Architecturally, this UNESCO World Heritage Site is an everlasting icon of the Mughal style blended with design elements from India and Central Asia. Good to know: Red Fort is open Tuesday to Sunday from sunrise to sunset. Entry fee for foreign visitors is priced USD 7, and there is an additional fee for filming. Prices for the daily light and sound show are USD 1. Fun fact: Red Fort was originally known as Qila-e-Mubarak, meaning 'Blessed Fort' and is the largest historical monument in Delhi.
