Islamic style, as the emperor had recently been campaigning near Samarkand. Singularly, the innumerable Chaukhandi tombs are of eastern influence. Although constructed between 16th and 18th centuries, they do not possess any similarity to Mughal architecture. The stonemason works show rather typical Sindhi workmanship, probably from before Islamic times. Later Mughal architecture, built under Aurangzeb (ruled 1658–1707), include the Badshahi Mosque in Lahore and Bibi ka Maqbara in Aurangabad. By the late 18th century the style was effectively over. However, by this time versions of Mughal style, often called "post-Mughal", had been widely adopted by the rulers of the princely states and other wealthy people of all religions for their palaces and, where appropriate, tombs. Hindu patrons often mixed aspects of Hindu temple architecture and traditional Hindu palace architecture with Mughal elements and, later, European ones. Major examples of Mughal architecture include: Tombs: Taj Mahal, Akbar's Tomb, Bibi ka Maqbara, Safdarjung Tomb and Humayun's Tomb Forts: Red Fort, Lahore Fort, Agra Fort and Idrakpur Fort Mosques: Jama Masjid of Delhi, Badshahi Masjid and Moti Masjid Gardens: Shalimar Gardens, Bagh-e-Babur and Verinag Garden Caravansaries: Akbari Sarai and Bara Katra Bridges: Shahi Bridge, Mughal Bridge, Athpullah and Barapullah Milemarkers: Kos Minar Taj Mahal The most well known example of Mughal architecture is the Taj Mahal. It was built for the wife of Shah Jahan, who died in 1631. The main ideas and themes of garden tombs had already been explored by earlier Mughal emperors, and this was the culmination of all those previous works into a national landmark. The 171 meter white tomb rises above a reflecting pool. Red Fort The Red Fort in Delhi is also an important example of Mughal Architecture. It was built during the zenith of the Mughal Empire under Shah Jahan. It was designated a UNESCO World Heritage Site in 2007. As one of the largest forts in India, it served as the official residence of the emperor for nearly 200 years. Post-Mughal Islamic architecture Following the collapse of the Mughal Empire after the Mughal-Maratha Wars, the emergence of the Sikh Empire and the invasions of Nader Shah, Ahmad Shah Durrani and the British East India Company, prosperous provinces of the Mughal Empire such as Awadh, Bengal, Hyderabad and Mysore emerged as powerful regional states independent of Delhi. In Awadh (encompassing modern eastern Uttar Pradesh), Lucknow emerged as a centre of Ganga-Jamuni culture and Urdu/Hindustani literature. The
