The architecture of New Delhi was the crowning glory of the British Raj. The architects of this new city were Edwin Lutyens and Herbert Baker. The bulidings of New Delhi were made of red sandstone and included features like domes, chhatris(kiosks), and jalis(trellised windows).
They designed a beautifully symmetrical city with the President's Palace atop Raisina Hill at centre, the city spreading out on all sides. There were office buildings. At the other end of RajPath was India Gate, built in memory of the british soldiers who died during World War 1. To the left of Viceroy's House was the Council of Chamber. Connaught Place, at the centre of the city was part of Lutyens' design Humayun's tomb Purana Qila, Qutub Minar and the Hazrat Nizamuddin were all made to be a part of New Delhi. Broad tree-lined roads, gracious public buildings, fountains and parks characterised British Delhi.
