Delhi is a spacious, open city that houses many government buildings and embassies, apart from places of historical interest. As well as being a starting-point for visiting Agra, the home of the Taj Mahal, or the cities and forts of Rajasthan, Delhi itself has much to offer. The architectural legacy of the Islamic conquerors is rich and varied, the colonial centre is imposingly impressive; there are some interesting museums and the city’s bazaars and shops offer a bewildering array of goods, from spices and silks to car spare parts. The city’s restaurants tempt the visitor with a wide variety of delicious food, which by Western standards is mostly very reasonably priced.Notable attractions in New Delhi include the Rashtrapati Bhawan, the one-time imperial residence of the British Viceroys; the India Gate, a memorial raised in honour of the Indian soldiers martyred during the Afghan and subsequent wars; the Laxminarayan Temple, built by the Birlas, one of India's leading industrial families; The Swaminarayan Akshardham temple; Humayun's Tomb; the Purana Quila, built by Humayun, with later-day modifications by Sher Shah Suri; Tughlaqabad, The ruins of a 14th century fort on the outskirts of town; Qutab Minar, built by Qutb-ud-din Aybak of the Slave Dynasty; and the lotus-shaped Bahá'í House of Worship.
