Somanathapura's history revolves around the magnificent Keshava Temple, commissioned by Soma, a dandanayaka (commander) in the Hoysala army, during the reign of King Narasimha III in the 13th century. The temple's construction marked a significant period of Hoysala architectural achievement. Inscriptions on the temple walls reveal details about its construction, the patronage of Soma, and the dedication to Lord Keshava. The Hoysala dynasty, known for its patronage of art and architecture, left a lasting legacy with the Keshava Temple, which stands as a testament to their artistic prowess and religious devotion. Despite the decline of the Hoysala empire, the temple has endured through centuries, preserving its intricate carvings and historical significance.
