The Kasturi Rangappa Nayaka Fort in Sira in Tumkur district of Karnataka is named after the Nayaka ruler Kasturi Rangappa Nayaka, who had ruled over Sira in the early 17th century as a palegar under the Vijayanagar Empire. After their rule, the fort and the Province of Sira came under the control of several rulers. Restoration works have been carried out by the Archaeology Department of Karnataka.
