Very close to Rashtrapati Bhavan is situated the imposing Parliament House building another creation of the genius of Lutyens and Baker. It is a huge circular, colonnaded building where the sessions of Parliament are held.It has a dome-shaped circular Central Hall and three semi-circular structures, the Rajya Sabha, (Upper House), Lok Sabha( Lower House) and the library. A verandah with as many as 144 columns and the boundary wall has blocks of sandstone carved in geometrical patterns, that remind one of the Mughal jaalis.No one is allowed to enter the gates without a valid permit and to obtain a visitor's pass, Indian nationals need to apply to the Parliament Secretariat and foreign nationals through their embassies or high commissions.
