New Delhi is an urban district of Delhi which serves as the capital of India and seat of all three branches of the Government of India. The foundation stone of the city was laid by Emperor George V during the Delhi Durbar of 1911. It was designed by British architects, Sir Edwin Lutyens, and Sir Herbert Baker. The straight and diagonal pattern of the broad tree-lined avenues in New Delhi, with extensive green spaces and wide vistas, contrasts sharply with the crowded, narrow, and winding streets characteristic of Old Delhi. The main east-west axis of New Delhi is Central Vista Park, which is flanked by government buildings, museums, and research centers in a parklike setting.
