I found these pics posted on another site -- an interesting little photologue showing the awesome Indo-Saracenic architecture of Lutyen's New Delhi.
This area of New Delhi comprises the Parliament, Rashtrapati Bhavan (Presidential Palace, residence of the President of India), Rajpath (Kings Way, which connects India Gate to R.B.), and the Secretariat buildings.
Rashtrapati Bhavan is the large domed structure in the latter pics, where the relief ceremony takes place. The road and building in the beginning of the photos is the Rajpath and one of the Secretariat buildings, two of which flank the road.
Here's a description of the ceremony:
The Changing of the Guards ceremony dates back several hundred years. The ceremony features The President's Bodyguard, the Indian Army's oldest and senior most regiment, as well as India's Household Calvary regiment, raised in 1773 and with traditions dating back over a hundred years earlier, as well as soldiers from the Rajputana Rifles, India's senior most rifles regiment, raised in 1775.
Soldiers of the band and marching contingents are assigned from different regiments for duty over a short period of time in rotation. It is considered an especial honor for the regiment and is a matter of great pride. The following pictures of the ceremony, the Regimental Contingent features soldiers from the Assam Regiment, one of India's youngest but one of the most decorated infantry regiments, which was raised in 1941 and is composed of soldiers from and draws traditions from the India's northeast states.
The Changing of the Guards ceremony takes place every morning, but on Saturday mornings a larger traditional ceremony is held. At 0615, the sounds of martial music, marching of footsteps and hoof beats arise from within the complex and the New Guard comprising a contingent of Indian Army Regiment (in this case, Assam Rifles), Rajputana Rifles and mounted troops of The President's Bodyguard accompanied by the regimental brass band emerge on to Rajpath, marching to the strains of "Vijay Bharat," while the Old Guard marches off to "Sare Jahan Se Achha"
The two Guards meet and Compliments are paid by the New Guard, which assumes charge. The balance of the Old Guard marches off along with the band playing "Amar Jawan."
