Tirupati City is located in the southeastern part of Andhra Pradesh State. It lies about 152-km northwest of Chennai in the Palkonda Hills. Tirupati is known as the abode of the Hindu god Venkateshvara (also spelt as ‘Venkatesvara’), “Lord of Seven Hills“. About 10-km northwest of Tirupati, at an elevation of 750m, is the sacred hill of Tirumala, which was considered so holy that before 1870 non-Hindus were not permitted to ascend it.
