Chandragiri Fort In Tirupatistands as a testament to the glorious past of Tirupati, a city known worldwide for its spiritual significance owing to the revered Venkateswara Temple. Situated in the Chittoor district of Andhra Pradesh, India, Chandragiri Fort is not just a historical relic but a symbol of power, culture, and architectural brilliance. Its origins date back to the 11th century when it served as a strategic stronghold for the Yadava Rayas, the rulers of the region. However, it was during the reign of the Vijayanagara Empire in the 14th century that Chandragiri Fort gained prominence, becoming the secondary capital of the empire under the rule of Saluva Narasimha Rayalu.
