The Nannesvara Temple, also known as the Nanneshvara Temple, is an 11th-century Hindu shrine located in Lakkundi, Gadag district, Karnataka. It is recognized for being the earliest example of the imperial-style architecture of the Kalyana Chalukyas, incorporating elements from both North Indian and South Indian architectural traditions. Positioned directly to the west of the more elaborate Kasivisvesvara twin Temple, the Nannesvara Temple is a significant historical monument, protected by the Archaeological Survey of India as a site of national importance.
