The Archaeology of Ayodhya concerns the excavations and findings in the Indian city of Ayodhya in the state of Uttar Pradesh, much of which surrounds the Babri Mosque location. British-era studies In 1862–63, Alexander Cunningham, the founder of Archaeological Survey of India (ASI), conducted a survey of Ayodhya. Cunnigham identified Ayodhya with Sha-chi mentioned in Fa-Hien's writings, Visakha mentioned in Xuanzang's writings and Saketa mentioned in Hindu-Buddhist legends. According to him, Gautama Buddha spent six years at this place. Although Ayodhya is mentioned in several ancient Hindu texts, Cunningham found no ancient structures in the city. According to him, the existing temples at Ayodhya were of relatively modern origin. Referring to legends, he wrote that the old city of Ayodhya must have been deserted after the death of Brihadbala "in the great war" around 1426 BCE. When King Vikramāditya of Ujjain visited the city around first century CE, he constructed new temples at the spots mentioned in Ramayana. Cunningham believed that by the time Xuanzang visited the city in 7th century, Vikramaditya's temples had "already disappeared"; the city was a Buddhist centre, and had several Buddhist monuments. Cunningham's main objective in surveying Ayodhya was to discover these Buddhist monuments. In 1889–91, an ASI team led by Alois Anton Führer conducted another survey of Ayodhya. Führer did not find any ancient statues, sculptures or pillars that marked the sites of other ancient cities. He found "a low irregular mass of rubbish heaps", from which material had been used for building the neighbouring Muslim city of Faizabad. The only ancient structures found by him were three earthen mounds to the south of the city: Maniparbat, Kuberparbat and Sugribparbat. Cunningham identified these mounds with the sites of the monasteries described in Xuanzang's writings. Like Cunningham, Führer also mentioned the legend of the Ramayana-era city being destroyed after death of Brihadbala, and its rebuilding by Vikramaditya. He wrote that the existing Hindu and Jain temples in the city were modern, although they occupied the sites of the ancient temples that had been destroyed by Muslims. The five Digambara Jain temples had been built in 1781 CE to mark the birth places of five tirthankaras, who are said to have been born at Ayodhya. A Svetambara Jain temple dedicated to Ajitanatha was built in 1881. Based on local folk narratives, Führer wrote that Ayodhya had three Hindu temples at the time of Muslim conquest: Janmasthanam
