Hoysaleswara temple, also referred simply as the Halebidu temple, is a 12th-century Hindu temple dedicated to Shiva. It is the largest monument in Halebidu, a town in the state of Karnataka, India and the former capital of the Hoysala Empire. The temple was built on the banks of a large man-made lake, and sponsored by King Vishnuvardhana of the Hoysala Empire. Its construction started around 1121 CE and was complete in 1160 CE. During the early 14th century, Halebidu was twice sacked and plundered by the Muslim armies of Delhi Sultanate from northern India, and the temple and the capital fell into a state of ruin and neglect. It is 30 kilometres (19 mi) from Hassan city and about 210 kilometres (130 mi) from Bengaluru.
